Question

So i am trying to connect to 1 server which is SSL enabled using self signed certificates. Which connecting to it,I am getting this. Can someone help in this? These are the SSL logs. And in java code, i am ignoring any certificate issues.

Answer 1

Using a browser to access https://performance.infoworks.technology and checking the certificate confirms that the certificate is self signed.

It is also signed by an issuer which is not trusted: IW Root CA .

You need to make IW Root CA available on the client, put it into the certificate storage which is used in the context of running your java application to make sure is trusted at the time the request is made.

Alternatively, for testing only (,). you can disable the certificate validation when making the request.
