www.bolt.gmgtrans.eu is a second-level subdomain so is not covered by the Universal SSL certificate (which only covers gmgtrans.eu and *.gmgtrans.eu).

If you need this to be proxied, then you will have to use Advanced Certicate Manager. It’s usually better just not to use www.bolt... and stick with bolt.gmgtrans.eu.

Other things to note:

  • use only “Full (strict)”, not “Full” SSL/TLS mode
  • the mail subdomain needs to be a “DNS only” A record instead of a proxied CNAME to your domain. As does ftp if you actually use it for FTP.

Thx. I managed to fix it by changing to bolt.gmgtrans.eu without the www protocol. Thank you
