hi @kaanpeker

Create a new certificate with all your domains and reinstall

You have not articulated how you obtained the certificate intially so that’s the best help I can offer.

thanks a lot!

I try to understand is there any limitation to create a cert for a specific domain and subdomains and then remove it from system for adding new subdomains to that particular domain ?

I use a web interface and dashboard for doing this on Synology DSM 6.1. The certification can automatically add and remove via this interface. I do not create or modify any configuration files.


#4

and forgot to ask :slight_smile: what is the limit for subdomain number ?

The rate limits for new certificates are described at

https://letsencrypt.org/docs/rate-limits/

You can get 100 names in a single certificate, but you can only get a limited number of separate new certificates per week that cover names within the same domain.


#6

so what is the best and the rightest way to add new subdomains (a1.example.com / a2.example.com) to the existing certificate issued by Let’s Encrypt ? do I need to remove the certificate from my Synology Web Server and re-issue certificate with new extended subdomains ? or is there any way to add new subdomains to the cert without re-issuing certificate?


#7

Certificates can only ever be changed by reissuing them, although some software typically hides this fact from the user.
