Some of the users of the new IM server I’'ve set up are experiencing an issue where at times users are showing as offline even though they are logged in and online. 1 user sees all/some contacts offline while another user see some of those same contacts as online (which they should be). All clients use the newest spark.
It’‘s not a one shot deal though. It’‘s different users, seeing different people offline. It seems to be a more spark related happening as well. I’'ll have to go fill in more data on the thread I created there.
What is your actual configuration environment of your server and clients. I had a similar issue with one of my clients from my test group. The solution was twofold.
Use the canotical name of the server as it appears in DNS (chatserver.domain.com) everywhere: Server config and client.
