I keep getting this message across all of the email accounts associated with this Outgoing Server:

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) <server_address> was lost in the middle of the transaction. Try again.

I've tried restarting the computer but without any success. I'm on Thunderbird 91.10.0.

Strangely, I can go to the webmail address through CPanel and send emails through that without issue, but trying to use Thunderbird to send mail fails 100% of the time. This issue has been ongoing since Thursday, June 23rd.

Any assistance or advice would be tremendous.

Thank you!

I disabled SSL security and set the port to 587 and I can now send email, but changing it back to SSL security immediately removes the functionality again.

What gives? Is the password incorrect or something? How would it have changed? It worked fine Wednesday night, but Thursday morning it was bad.
