Domain Timeout after new Letsencrypt cert

Nextcloud version (snap 13.0.2):
Operating system and version (Kubuntu 18.04):

I clean installed Kubuntu and didn’t save my certs. I reinstalled nextcloud snap / ddclient and ran lets encrypt to get a new cert and opened up my ports again (port forwarding still the same on my router) and added trusted domains via .occ. When I try to access the server through my domain I get a timeout error. I can access it locally. I can ping and traceroute the public ip but telnet also has a connection timeout error. Any ideas?
