Hello,
We use jabber on-prem. Remote users are using MRA to connect. We have some users report getting a certificate popup for u2c-a.wb2.com when in public locations such as the airport. I am trying to understand why Jabber tries to connect to this server
I verified the users are putting in the correct jabber domain when entering the username and the logs show its able to find the domain services.

However the connection to u2c-a.wbx2 occurs before the collab edge lookup. Is this jabber trying to connect to jabber cloud service because of some issue connecting to MRA?

Hello mate,
As you said "However the connection to u2c-a.wbx2 occurs before the collab edge lookup. Is this jabber trying to connect to jabber cloud service because of some issue connecting to MRA? ", Jabber/Webex Teams will always try to connect FIRST to Webex Cloud services independently from where user tries to login. If user account is not found as valid Webex Cloud address then it will continue the login flow.
Hope it helps
