Connection error Certificates. Works, doesnt work

Thunderbird Connectivity

Connection error: Certificates. Works, doesn't work Thunderbird 157 intermittently fails to connect to imap.shaw.ca:993 with SEC_ERROR_UNKNOWN_ISSUER. It affects two separate Shaw email accounts, while Shaw Webmail continues to work normally.

Installed a week ago to replace MS365/ outlook Worked fine. But now it's acting up. Both my Shaw emails as well as my wife's email on her computer.

This does not happen with my domain emails.

The only reply I got was to change the trust setting in your software. That's not a solution; that's a problem in the making.

ATT has had problems. They should have fixed it by now.
