RTC 502 Collaborator 8.5 issue

0
Norman Dignard (356●6●96●177) | asked Nov 17 '16, 1:03 p.m.
Env - RTC 502ifix14/Smartbear Collaborator 8.5.8502. Both running on same RHEL 6.4 server, using Oracel as a backend. Thsi setup has been in place and running for a year or two.
Yesterday users noted that they could not create a code review by a state transition of a work item.
I looked on this but am failing to find the problem/solution.   I've restarted both apps, the server itself as well a the reverse proxy server (squid).    I can cross-navigate between Collab reviews and RTC workitems for existing reviews. we just can't create new reviews.

All that i see in the ccm.log is:

Nothing has changed on the server or the applications.
Anyone have a clue as to what causing this and how to fix it?

Note: the URL did not copy correctly for the above it should have read:

ERROR com.smartbear.collaborator.rtc.process              - unexpected throwable
com.smartbear.ccollab.client.CollabClientServerUrlConnectionException: Could not connect to a Collaborator Server at http://jazzweb.deveng.local:8080/xmlrpc/secure: Does not appear to be a running Collaborator Server.

It's a shame that Smartbear does not reveal the error/exception that caused the communication exception after it captured it. Just a wild guess, as the URL contains the word "secure", I suppose you should provide a user name and password for it, so is it possible that the password expired?

After fixing a problem on our proxy server (incorrect host entry) the issue went away.
