Chat not connecting

I have a new eM Client install that I installed yesterday. Added a gmail account, and setup a contact with two gmail accounts for IM. It worked okay yesterday, but today my Chat won’t connect when I try to go online. Restarted eM Client. Also added XMPP logging. This seems like the relevant portion of the log showing the error -

Maybe I should also mention… on that contact I added with two gmail accounts - one personal, one business, one of those is a username@gmail account. The other is the person’s account at a school district, using the school district’s domain (username@xyzusd.org) - but the underlying account for it is a gmail account that is providing the email services. I’m not sure this matters, though, as it seems more like the problem is with my gmail account not connecting with the google chat service. But when I log in direct to gmail with my account, the chat piece is working there. So login, password, etc… all seems fine.

Nevermind on this one for now. Realized I hadn’t rebooted that system to see if that helped. Rebooted, and now it does connect. Will be back later if it was only a temporary fix and goes back to not connecting again.
