Apache automatic shutdown

My VPS is running on CWP 0.9.8 and AlmaLinux 9.5. It has been running for several months, and everything was working fine before, but now Apache often stops automatically. When Apache stops automatically, I see the following entries in the error log

[Tue Nov 25 03:15:10.714565 2025] [ssl:warn] [pid 2664906:tid 2664906] AH01909: webmail.mydomain.com:443:0 server certificate does NOT include an ID which matches the server name

But the subdomain webmail.mydomain.com does not exist, and I haven't applied for an SSL certificate for this domain either.

And
It will also automatically stop when someone scans.

Please help！

If you don't use the webmail SAN, you should delete that configuration detail from the AutoSSL setup. (If you don't have a valid DNS A record or CNAME for it, uncheck "webmail" from the list of SANs -- as I do with the "cpanel" SAN.)

I checked, and I did not set up certificates for mail, webmail, ftp, or cPanel services. However, I still deleted the existing certificates and reapplied for my website (unselecting mail, webmail, FTP, or cPanel).

Let me see if this error occurs again.
