Gmail connection issue

[JuergenAuer]

Hi @Doidel

@Doidel

But Gmail responds with:

Server returned error: "SSL error: ok IP address "162.246.23.164" not found in SANs"

Or, when I try to use port 143 with the checkbox ticked for “Always use a secure connection (SSL) when retrieving mail.”, I get the error:

Server returned error: "SSL protocol error. Please try disabling SSL, or contact your other provider to verify the correct port settings."

looks like a bug of GMail.

Connecting a server there is always the ip address used. But then the client (GMail) should send the hostname, so the server is able to select the correct certificate. That's SNI - Server Name Indication.

So the server checks the list of certificates to see, if the hostname is included in the SAN list of one certificate.

But the error message says: GMail sends the ip addresss as hostname.

Your certificate has only domain names, not ip addresses. So that can't work. But it's not your error, it's general impossible.

Checking your connections that's good - https://check-your-website.server-daten.de/?q=bhooks.com

There was another user - a problem with GMail - "SSL error: Leaf certificate is expired"

Thunderbird worked, GMail not.

Or you have a configuration error, so you use the ip address in your gmail-configuration. But I don't think that.
