For what combination of domains/subdomains have you been trying to get a certificate when you hit the identical certificate limit?

Hi @alalili

most users of this forum don’t use Synology, so it may be better to ask in the Synology forum.

What says that i (Subject Alternative Name): May be you must use your main name too.

But that’s speculative, that’s more a Synology problem.

Try putting for you domain name and for the subject alternative name. Theoretically the tool you are using for your certificates will later add your domain name ( to the list of subject alternative names for you since it needs to be in that list too. If there’s a setting somewhere to redirect http to https that would also help.
