It’s working here. Can you explain it with more details? What client do you use and how are you doing your group chat, step-by-step. Also have you tried to restart Openfire? Any related errors in error.log?
On Spark, an Group Chat window does not appear when a Group Chat icon is clicked from a Chat window.
On Pandion, an Group Chat window can be opened but the connecting status is staying in “connecting” when a Group Chat icon is clicked from a Chat window.
On the both, the existing Group Chat room can not be detected.
Also, I could not find any related error messages on the error log.
