You’ll want to contact your SMTP provider for assistance as that is coming directly from them. Link to comment Share on other sites More sharing options...

But all three options SSL, TLS, and plaintext still gives me the same connection error code. Is there something special I have to do with certificates or something?

I switched to outlook now with the same error code. Is there a server setting i should check for this? Link to comment Share on other sites More sharing options...
