We've been using Cisco Jabber desktop client without any trouble for several months. Recently (past two days) I've had a couple of users with 10.5.5 client start seeing the error message "Cannot communicate with the server". This is using the default Jabber client configuration Makes no difference if the user is or isn't a UCM integrated user or if the user is or is not connected to our corporate VPN.
I've updated one of the clients to 10.6 but still see the same error. In the update, I first uninstalled 10.5.5 then installed 10.6.
Both clients are teleworkers using their home internet services but not seeing trouble with web browsing, e mail or VPN.
One client for a test logged into a Remote Desktop server here in office and was able to log into Jabber so it's not an account issue, no changes reported on either client PC.
For both clients as a temporary fix I've installed Cisco IP Communicator but I worry that having two of this error in one day, I'm probably going to see more of it soon. Also the users themselves are not happy with the CIPC.
Any suggestions on what to look for (No idea what server(s) Jabber uses by default) or what type of logs I can send to Cisco for them to review will be appreciated.
