I have been having issues with Gmail and sending mail as over the last few days. When sending email as (from my domain domain.org) I get a return email stating "TLS Negotiation failed, the certificate doesn't match the host. " Now I have been sending mail as through Gmail with multiple accounts for a very long time.
So I go into accounts and import and any of my accounts adding, or updating passwords I get an error saying Server returned error: "TLS Negotiation failed, the certificate doesn't match the host., code: 0"
So here is what I have tried as settings - I typically have used the domain name as the smtp host - domain.org or mail.domain.org I have also tried the host.com and get the same message. I have used both SSL and TSL ports 465 for SSL and 587 TLS.
So with troubleshooting, I added these accounts to outlook (the app) and Bitdefender through up an error as well saying "OUTLOOK.EXE attempted to establish a connection relying on an unmatching security certificate to domain.org. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one" and I went ahead and added the exception and outlook did give me "
The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect. I believe that was using the domain name. Now in outlook if I use the hostname I get 0 error. But if I do that in Gmail I get error.
Any thoughts? My data center is out of ideas as well.
