Got kicked out of live chat and says the chatroom is closed until the next session.

I just randomly got kicked out of the support chat at the link below. It told me the session was over and that the next one would happen later. This is obviously not the case as the session is still happening. The listing of sessions says it’s still open, but when I try and join, it says the session is closed.

Please help figure this out, as it continually happens to me. I was in the middle of getting Vladislav’s help with an issue we’re having and this unreliable chat tool is killing our productivity.
