Thunderbird not receiving or sending emails after upgrade...

more options

Thunderbird just stopped sending/receiving emails. I'm running 91.2.1. It also seems to not be able to check for updates. I can access all of the emails via their web interfaces, but nothing is working in Thunderbird....including the account hooked up to Gmail.

Thunderbird would also not go into 'Troubleshoot Mode', so I restarted computer a couple of times and now all seems to be good???
