Cause

The error was an SSL communication failure and was related to the subject(CN) of the server certificate of Central. The SSL communication failed the host verification in the Studio side.

 

Fix

One of options would be to replace the current Central certificate with a new one with CN='<hostname_for_remote_debugging>'.

Another quick option would be to set ‘-Dssl.verifyHostName=false’ in Studio.l4j.ini.
