PMS SSL Uses *.plex.direct Let’s Encrypt SSL certificate instead of custom configured certificate

Hello. Your proposal is close to the procedure I use since OpenSSLv3.0, as explained here.

But it doesn’t explain why PMS refuses to consider it now, even if it’s compliant to minimum requirements.
Gandi certified the SSL with Digicert, Infomaniak uses Sectigo (Comodo) to certify it. I don’t know if there is a link, but with Gandi it perfectly worked.

But Gandi decided to at least double there prices (for the domain, SSL, mailboxes…) so I decided to change at the global renew.

But now that issue…
