PKIX path building failed - on valid let's encrypt certificate

I noticed today, that my services reject APIs certificate. It's not a self-signed certificate but one issued by let's encrypt. It looks fine in browsers and on some online cert checking tools, I found. It's been running just fine last week - but somehow stopped doing so over the weekend. It's Java 12 (tried OpenJDK on Mac, Linux and OpenJ9 on Linux)
Do you guys have any idea on how to debug (or even fix) this? I've checked on various

Has the certificate expired? The fact you said it stopped over the weekend suggests that it might be.
I had the same issue and this was the cause. I noticed that when it couldn't find the valid certificate, I'd get: SEVERE: I/O Exception javax.net.ssl.SSLHandshakeException: .
However, when the required certificate could be found BUT had expired I'd receive the same SEVERE: I/O Exception. sun.security.validator.ValidatorException.
I hope this helps.

I also tried adding the FiddlerRootCertificate to the keystore, but it still threw this error.
What am i missing here?
FYI, i am writing a simple script that downloads object from S3 bucket.

The reason for this error either you have invalid access and secret key pair Or you are blocked out from accessing AWS servers from your network

Cannot access Webservice under SSL from Java

I have a web service that runs under SSL using an SSL wildcard certificate that was signed by thawte. I can see the thumbprint for the thawte primary root cert in cacerts, however when I try to access my cert I get an exception (see below)
If I import the cert into cacerts it works. How can I access my web service without importing the cert into cacerts? Shouldn't Java trust my cert since it's signed by thawte? Or do I need to include every intermediate certificate into cacerts?
This is the code I am using to call the webservice:
QName serviceName = new QName("http://myservice.test.com/myservice", "MyService");
QName portName = new QName("http://myservice.test.com/myservice","MyServiceSOAP");
URL serviceUrl = new URL("https://myservice.test.com:443/myservice/services/MyServiceSOAP?wsdl");
Service service = Service.create(serviceUrl,serviceName);
myService = service.getPort(portName, MyService.class);
And the error trace is:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
This exception is usually due:
Incomplete trust path for the server certificate: the server certificate is probably not trusted by the client. Usually the fix is to import the server certificate chain in into the client trust store
Bad server config, like certificate chain incomplete. In the case the fix is on server part
Thawte is by default on cacerts, so probably the problem will be incomplete chain. You can verify the server with SSLLabs check for errors in 'certificate' or 'certificate chain'.
If the chain is correct, then download, and check whether or not the site certificate is in cacerts. The simplest way to do is using the GUI tool portecle

I am trying to use SSL and avoid any certificate validation as I am unable to install any certificate on the client.
Any idea?

Consider building your MongoClientOptions with a custom SSLContext. The latter one can be build using SSLContextBuilder from Apache HttpCore:
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(TrustAllStrategy.INSTANCE)).build();
There is also an option to use TrustSelfSignedStrategy.INSTANCE or implement your own depending on your setup.
