JMeter 4.0 : While recording java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source)

I'm using JMeter 4.0 software.
I used recording template for the same.
I also set proxy (i.e. localhost) and Port (8888 which is also set in JMeter HTTPS Test Script recorder) in a browser(Internet Explorer).
After that I click on start button in JMeter popup appeared (Certificate). I also install the certificate and import that in a browser.
but facing following issue in browser.

What could be causing this?

There could be a problem in loopback (localhost) for Windows 8 users that need to install a new Adapter:
The Microsoft Loopback Adapter was renamed in Windows 8 and Windows Server 2012. The new name is "Microsoft KM-TEST Loopback Adapter".
Resolution
When using the Add Hardware Wizard to manually add a network adapter, choose Manufacturer "Microsoft" and choose network adapter "Microsoft KM-TEST Loopback Adapter".
You can try to record using firefox guide if this doesn't help you.

Can someone please explain why I am getting this error. The same was working few days back.

I was facing similar issue but the difference was, I was using the url with https like https://start.spring.io/ which was causing same error.
I tried this url in to browser and able to access the Spring Starter.
When I changed the URL to http like http://start.spring.io/ in eclipse it's start working and I could create the required Project as well.

This is a tough one. It depends on which part is timing out due to the environment you are in.
Most probably you are encountering a connect timeout at the TCP level due either firewall issues or a dead application with its socket still up.
The overall connecttimeout for the JVM is set to -1, so infinite by default. Hello thread leaks.
sun.net.client.defaultConnectTimeout (default: -1)
You can find the documentation for Java oracle network parameters here: https://docs.oracle.com/javase/8/docs/technotes/guides/net/properties.html
The jmx/rmi specific documentation sadly doesn't have a connect timeout setting at that level. But they have a bunch of other controls on the read time-out: https://docs.oracle.com/javase/8/docs/technotes/guides/rmi/sunrmiproperties.html
You can test this while developing with something as simple as using netcat and pointing your app over to the localhost port:
# creat socket on port 3333
netcat -l 3333
# now point your app on the socket
# and you should be able to reproduce
This will stimulate a dead app or firewall block on the port.

Just add the Following System property - "-Dsun.rmi.transport.tcp.responseTimeout=60000"

Network is unreachable?

I want to run a cyc (opencyc) Java class, but when I run this class I got an error mentioning that the network is unreachable. I am working on NetBeans 7.0 and opencyc 2.0 win 32 version. I am using localhost (127.0.0.1) to test. The error is below.

at org.opencyc.api.CycConnection$ConnectionTimer.run(CycConnection.java:1351)
Why is this happening? How can I connect to the cyc?

The problem is that your network settings do not allow you to connect to this machine. This is not a Java problem as such.
try
ping {hostname}
until this works, there is nothing you can do in java to work around this.

If you have the same version I have, it's trying to establish a connection to a Cyc image with the hostname and port defined by
CycConnection.DEFAULT_HOSTNAME
CycConnection.DEFAULT_BASE_PORT
You can find the proper values to use by evaluating the following in your Cyc image:
(get-machine-name)
*BASE-TCP-PORT*
Hope this works for you.

A dev on my team encountered this today, only their machine is seeing this issue out of many on the team.
Through much debugging we eventually discovered that localhost would not resolve for some reason. It would work in some JVM contexts and fail in others so it was completely inconsistent.
Replacing localhost with explicitly 127.0.0.1 fixed the issue. My hunch is that something was different with a local network and IPv6 perhaps, but we still don't really understand why this is the fix.

java.net.SocketException: Software caused connection abort: recv failed, with java.net.SocketException: Connection reset [duplicate]

This question already has answers here:
Official reasons for "Software caused connection abort: socket write error"
(14 answers)
Closed 5 years ago.
I'm getting an exception in my Java, Hibernate, MySQL project within Netbeans IDE.
I've done some digging to try and fix this strange Socket exception, to no avail.
Some forum solutions suggested implementing a c3p0 connection pool for Hibernate. No fix.
Others suggested disabling AV and firewall (!!) as these could interfere with the socket connection. No fix.
I've tagged this question with Hibernate, as I'm not certain that hibernate is the cause, but the exceptions occur on a Hibernate call (running a query). Other Hibernate code in the app works fine. The Hibernate version is 3.2 .
The exception:

Help would be much appreciated. This is a bit of a strange one.
Thanks.

In my case, I was using Tomcat. Right click on Tomcat in Server list and then click properties, then uncheck "Enable HTTP Monitor". This solve my issues

There's a Microsoft Knowledge Base article about this, see if you can find it. Basically this is a result of prior errors writing to the network by the peer that gets the exception. Indicates a network problem rather than software.

It is a network error!
1.If you run your sparkstreaming on windows.just run:
ncat.exe -lk 7777
and download ncat.exe at https://nmap.org/ncat/
2.If you run your sparkstreaming on linux.just run:
nc -lk 7777
and make sure you have install on your linux
