Selenium & Java - specified proxy ignored

I am learning selenium testing and have encountered my first problem after few hours :D
Objective: add a proxy into my selenium program so that it will not access the internet straight from my router.
(Proxy- running tor browser on localhost. Works with other web scrapers smoothly)
The problem is, it seems like program does not see proxy settings or goes around it. Navigating program to "check ip" websites shows original ip, not changed one by proxy.
My code: [as in documentation https://www.selenium.dev/documentation/webdriver/http_proxies/]
Proxy proxy = new Proxy();
proxy.setHttpProxy("127.0.0.1:9150");
ChromeOptions options = new ChromeOptions();
options.setCapability("proxy", proxy);
Then I tried several other approaches found online (including a deprecated one)
/*String proxy = "127.0.0.1:9150";
ChromeOptions options = new ChromeOptions().addArguments("--proxy-server=http://" +proxy);
*/
/*String proxy = "localhost:9150";
Proxy p = new Proxy();
p.setHttpProxy(proxy);
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(CapabilityType.PROXY, p);
*/
and then it goes into driver parameter (commented ones are using options and cap)
WebDriver driver = new ChromeDriver(options);
Using the documentation code I do not get any error. It just does not change ip.
I tried everything I could think of but without success.
Notes:
ip & port are correct
websites are accessed after setting up proxy.
using commented code (first block, two lines) returns "This site can’t be reached" in chrome and " org.openqa.selenium.WebDriverException: unknown error: net::ERR_TUNNEL_CONNECTION_FAILED" in console
same code as note 3) but protocol changed to https "...https://" +proxy);" returns "No internet" in browser and "org.openqa.selenium.WebDriverException: unknown error: net::ERR_PROXY_CONNECTION_FAILED" in console

Your troubleshooting, may have highlighted the cause. 3) shows that it could not create the tunnel with your proxy using http. 4) shows tunnel created using https, but proxy connection failed. So it is probably looking for some type of creds.
Update your code to add SSL proxy:
Proxy proxy = new Proxy();
proxy.setHttpProxy("127.0.0.1:9150");
proxy.setSslProxy("127.0.0.1:9150");
ChromeOptions options = new ChromeOptions();
options.setCapability("proxy", proxy);

Selenium + Proxy = Fail

Proxy not working in Selenium
First of all i use free proxys from proxyfish (maybe thats the problem alrdy) https://hidemyna.me/en/proxy-checker/ tells me theyre working.
I found lots of code/solutions, most is outdated (capabilities=options..) or not working for me.
Tried several code/proxys chrome/ff however https://www.iplocation.net/ and https://whatismyipaddress.com showing actual IP address (IPv4 and IPv6).
What I tried..
System.setProperty("webdriver.chrome.driver", "C:\\selenium\\chromedriver.exe");
System.getProperties().put("74.208.112.***", "8080"); //1st try
Proxy proxy = new Proxy();
proxy.setHttpProxy("74.208.112.***:8080"); //2nd try
ChromeOptions options = new ChromeOptions();
options.setCapability("proxy", proxy);
options.setProxy(proxy);
options.addArguments("--proxy-server=74.208.112.***:8080"); //3rd try
ChromeDriver driver = new ChromeDriver(options);
driver.get("https://www.iplocation.net/");
driver.get("https://whatismyipaddress.com/");
Solution:
proxy.setSslProxy("74.208.112.***:8080");
Is there a way to test proxy connection before using proxy?

Getting Request And Response Using BrowserMobProxy, Selenium, Firefox, marionette/gecko

I'm trying to get response and request using BMP's RequestFilter and ResponseFilter. However, when the webpage loads, nothing gets printed in the console.
Everything else seems to work though. Maybe BMP is not watching GeckoDriver?
I'm using Firefox 50.0, BrowserMobProxy 2.1.2, Selenium 3.0.1, and GeckoDriver 0.11.1
The testing code is below. Could someone please help me?
Thank you very much!
BrowserMobProxy server = new BrowserMobProxyServer();
server.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);
server.start();
int port = server.getPort();
server.addRequestFilter((request, content, info) -> {
String q = URLDecoder.decode(info.getOriginalUrl(), "UTF-8");
System.out.println("Request: "+q);
return null;
});
server.addResponseFilter((response, content, info) -> {
String type = response.headers().get("Content-Type");
System.out.println("Response: "+info.getOriginalRequest());
System.out.println(type);
});
Proxy proxy = ClientUtil.createSeleniumProxy(server);
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability(CapabilityType.PROXY, proxy);
capabilities.setCapability("marionette", true);
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
capabilities.setCapability(CapabilityType.SUPPORTS_JAVASCRIPT, true);
FirefoxProfile fp = new FirefoxProfile();
capabilities.setCapability(FirefoxDriver.PROFILE, fp);
String gecko = "d:/Programming/java/geckodriver.exe";
System.setProperty("webdriver.gecko.driver", gecko);
driver = new FirefoxDriver(capabilities);
driver.get("https://google.com");;

In Firefox 51 and lower, there is a bug/missing feature in Selenium 3's GeckoDriver that prevents Firefox from picking up the proxy settings when setting CapabilityType.PROXY on the DesiredCapabilities object.
However, you can still set the proxy settings directly on the FirefoxProfile. There's an example of this in one of BMP's tests. Since you're already using a FirefoxProfile object, this would probably be a sensible solution for you. It would look something like this (replace localhost with a hostname/ip address as appropriate):
FirefoxProfile fp = new FirefoxProfile();
fp.setPreference("network.proxy.http", "localhost");
fp.setPreference("network.proxy.http_port", server.getPort());
fp.setPreference("network.proxy.ssl", "localhost");
fp.setPreference("network.proxy.ssl_port", server.getPort());
fp.setPreference("network.proxy.type", 1);
fp.setPreference("network.proxy.no_proxies_on", "");
This geckodriver issue also discusses a few other alternatives to using CapabilityType.PROXY on the DesiredCapabilities object.
UPDATE
According to the mozilla bug report, this issue is fixed in Firefox 52, which is scheduled to be released on March 7, 2017. In the meantime, the solution with the FirefoxProfile should work with 51 (and lower), and should also continue to work with 52+.

Selenium (Chrome) and BrowserMob doesn't work for https

I have been trying to integrate BrowserMob to my selenium tests. It works fine with website that work on http, but with https websites the browsers stop working and the HAR file doesn't contain any requests.
When navigating to a https site I get this error on the browser.
"There is something wrong with the proxy server or the address is incorrect."
Here is my code.
public class Browsermob {
BrowserMobProxy proxy = new BrowserMobProxyServer();
#Test
public void browsermobtest() {
proxy.start(9091);
// get the Selenium proxy object
Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
// configure it as a desired capability
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);
System.setProperty("webdriver.chrome.driver", "C:/Users/Madis/Documents/chromedriver.exe");
WebDriver driver = new ChromeDriver(capabilities);
// enable more detailed HAR capture, if desired (see CaptureType for the complete list)
proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);
// create a new HAR with the label "google.com"
proxy.newHar("http://www.google.com/");
// open google.com
driver.get("https://www.google.ee/#gfe_rd=cr");
driver.findElement(By.cssSelector("#gb_70")).click();
}
#AfterMethod
public void Afterthetest() {
// get the HAR data
Har har = proxy.getHar();
File harFile = new File("C:/Users/Madis/Documents/har.har");
try {
har.writeTo(harFile);
} catch (IOException e) {
e.printStackTrace();
}
}
}

You don't need to specify the sslProxy on the Selenium Proxy object. ClientUtil.createSeleniumProxy does this for you, and in most simple cases it chooses a suitable default value (using InetAddress.getLocalHost(); if that's working for HTTP, it will work for HTTPS as well).
A few things to keep in mind:
You'll receive SSL warnings in the browser unless you either tell the browser to ignore cert errors (on Chrome, use the --ignore-certificate-errors command-line flag), or install the BMP CA in the browser's trust store (for Chrome on Windows, you must install it in the Windows trust store).
Depending on your version of Chrome and OS, you may need to specify an alternate user-data-dir using a command line option. For example, --user-data-dir=/tmp/insecurechrome.
BMP has its own source of trusted certificates (Java trust store + a recent list from Mozilla), so if you're trying to connect to internal websites with certificates issued by a private CA, you need to tell BMP to either trust the private CA or skip certificate validation using .setTrustAllServers(true).
The proxy must be started using .start(...) before calling createSeleniumProxy().
Combining all these things, your code would look something like this:
BrowserMobProxy proxy = new BrowserMobProxyServer();
proxy.setTrustAllServers(true);
proxy.start(9091);
// get the Selenium proxy object
Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
// NOTE: there is no call to .setSslProxy() here
// configure it as a desired capability
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);
System.setProperty("webdriver.chrome.driver", "C:/Users/Madis/Documents/chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArgument("--ignore-certificate-errors");
// replace 'somedirectory' with a suitable temp dir on your filesystem
options.addArgument("--user-data-dir=somedirectory");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver = new ChromeDriver(capabilities);
// [...]

I had this problem. After numerous trials, I got to know we have to add setmitmManager and upstream proxy if you are connected to corporate proxy. It worked for me.
Here is the example code.
BrowserMobProxy proxy = new BrowserMobProxyServer();
proxy.setTrustAllServers(true);
//Add below line if you are under corporate proxy.
proxy.setChainedProxy(new InetSocketAddress("XXX.XXX.com", 8080));
proxy.setMitmManager(ImpersonatingMitmManager.builder().trustAllServers(true).build());
proxy.start(9091);
// get the Selenium proxy object
Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
// configure it as a desired capability
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);
System.setProperty("webdriver.chrome.driver","C:/Users/Madis/Documents/chromedriver.exe");
WebDriver driver = new ChromeDriver(capabilities);
// your code to start, get har

You're confusing the browser mob proxy object and the selenium proxy object.
Your proxy variable proxy is the actual proxy which your browser will connect to.
Your seleniumProxy variable is an object which represents your browser's proxy settings.
You are telling your browser to use "trustAllSSLCertificates" as the address for your proxy server, which is why you are getting an error. Instead, you should tell browsermob (proxy) to trustAllSSLCertificates, and your sslProxy needs to reference your browsermob proxy.
Start the proxy like so:
public void startProxy() {
proxy = new BrowserMobProxyServer();
proxy.setTrustAllServers(true);
proxy.start(9091);
}
Start the driver like so:
public void startBrowserWithProxy() {
Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
seleniumProxy.setSslProxy("localhost:" + proxy.getPort());
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);
System.setProperty("webdriver.chrome.driver", "C:/Users/Madis/Documents/chromedriver.exe");
WebDriver driver = new ChromeDriver(capabilities);
}

I managed to get it to work. After adding log4j and debugging the browsermob logs the issue was caused by
Caught an exception on ClientToProxyConnection
java.lang.NoSuchMethodError: com.google.common.net.HostAndPort.fromHost(Ljava/lang/String;)Lcom/google/common/net/HostAndPort;
In order to make it to work I had to add a dependency to my maven project. This fixed this issue and I was able to see the capture the traffic on https sites aswell http sites.
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>20.0</version>
</dependency>

I hade a lot for capabilities, options and etc but it did not work
In my case, I changed exist dependency in pom
<artifactId>browsermob-core-littleproxy</artifactId>
to
<dependency>
<groupId>net.lightbody.bmp</groupId>
<artifactId>browsermob-core</artifactId>
<version>2.1.5</version>
</dependency>
and up "guava" version.
After that everything became good

Set Selenium proxy programmatically

In my automation project I need to set proxy server. I tried with system variable settings and profile setting for firefox browser. But those technique does not work for me. Please any one help me in this regard.
Note: I also tried with executing shell command using java but I got stuck when password is asked.

You definitely don't need to set any System-level properties. This is one way to do it in Firefox:
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.type", 1); // Manual proxy config
profile.setPreference("network.proxy.http", "proxy3.proxy.net");
profile.setPreference("network.proxy.http_port", 3128);
profile.setPreference("network.proxy.ssl", "proxy3.proxy.net");
profile.setPreference("network.proxy.ssl_port", 3128);
WebDriver driver = new FirefoxDriver(profile);
Or a more flexible, less browser-specific alternative:
org.openqa.selenium.Proxy proxy = new org.openqa.selenium.Proxy();
proxy.setHttpProxy("proxy3.proxy.net:3128");
proxy.setSslProxy("proxy3.proxy.net:3128");
DesiredCapabilities caps = DesiredCapabilities.firefox(); // or chrome() etc.
caps.setCapability(CapabilityType.PROXY, proxy);
WebDriver driver = new FirefoxDriver(caps);
