SMTP Settings
Sending of the message failed. Unable to communicate securely with peer: requested domain name does not match the server’s certificate. The configuration related to mail.wizardtower.com must be corrected.
this is the error I keep getting on my laptop, I can receive email fine just cant send out, I get the Certificate exception and add it, deleted all my local files after an uninstall and did a fresh reinstall same results. The annoying part is that on every other computer my account works fine but it's only on the new laptop that it won't double checked network stuff to make sure Thunderbird wasn't getting blocked by anything.
Help?

It is our own mail server and we updated our certificates recently, these settings work on every other device I've installed on including my phone. It works in other mail clients. Just not thunderbird my preferred one on this laptop. (windows 10 on each pc device, firewall exceptions set for mail clients)
Is this the 'self-signed certificate' bug that affects TB 78 but not 68?

It was, thank you.
So your Thunderbird is attempting to securely connect to mail.wizardtower.com.

Inspect the certificate - see the attached screenshot for instructions. What is the common name (CN) of the server's cert? Please post a screenshot of the Certificate Viewer window with that information visible. https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem
Are there any SANs in the server's cert? https://www.ssl.com/faqs/what-is-a-san-certificate/#content
