Hello! I have a Question about the Certificate Renewal on Synology.
I am using a website just for myself for some testing and stuff :).
I have all countrys blocked on my firewall except 1. The automatic renewal only works if let’s encrypt has access on port 80 and or 443?. I would like to only allow let’s encrypt to visit my NAS.
I also have a running mailserver with certificate.
Is there anyway i know which network or dns host i can give access to so the renewal works again?
Thanks in advance
