Error when connecting to an RTC Server

Hey all,

since yesterday everytime I try to connect to one of our RTC server with a Jenkins it throws me this exception:

One of my co-workers told me he heard of that problem and deleting the home folder and then reconfiguring the Jenkins should fix it. Alas, the problem still persists and I have no idea what I should do about it. Can some of you help me out?

=======================UPDATE=======================

This exception came up today once more. Does anyone have any more information about this issue? Google yet to yield any useful answers.

Cheers,
David
