Error CRJAZ2419E Handshake failure: how do I resolve it ?

I tried to add a connection to my social network in a given project area. I received error CRJAZ2419E.

I logged onto the server, tried to ping the server where the connection is located, and it came back.

I accessed the jazz.log and found this error stack:
