I have a working setup, but on every couple of builds one of the post build steps is not done.
Updating the version of the jira task.

What is see in the log is:

jira rest client get versions error. cause: hostname in certificate didn't match: <jira.tradologic.com> != <*.tradologic.net> OR <*.tradologic.net> OR <tradologic.net>

This is not happening on every build. Certificate is correct and connection to jira is working fine.
