HTTPS post to webmethods is failing

Hi All,
I know that this subjects sounds familiar and trust me i searched 2 days on this forum before opening a new post.

Here is my issue. My EAI partner is calling my service on webMethods via HTTPS post. I provided him with server and CA certs. He is calling my service via some JAVA script and he gets the following error :
“Unable to establish security context for this session”

Below is an excerpt from his trace log

He says that his java scripts internally converts the DNS name to IP address and since my certificates are issued with proxy name, they might be creating problems for the SSL handshake. One thing is clear connection is not an issue. The issue arises during the SSL handshake.

I changed my certificates and gave him new certs having the IP address of my server. But still he cannot call my service.

I heard that he is trying to import the certificates into his browser. Does he have to import it into his JAVA program?

What is the issue here? Can someone help?

What version of IS are you using? Increase SSL log level on your server, hope partner’s certificates are configured on IS

Did you try set all log levels to debug/Trace?

Have you restarted IS after configuring certs in the trusted path?
