Hi Father_Redbeard, more then two years later I have the same problem and I think still nobody wants to limit the access of nextcloud to the local network. I'm stuck with the following error on the initial config page (with i can access over my domain locally "The domain is not reachable on Port 443 from within this container. Have you opened port 443/tcp in your router/firewall? If yes is the problem most likely that the router or firewall forbids local access to your domain. You can work around that by setting up a local DNS-server." Also I get this error in the dockerlogs NOTICE: PHP message: Info: It seems like the ip-address of domain is set to an internal or reserved ip-address. (It was found to be set to '192.168.119.49') You got it working and iam wondering if you could share your NPM config? Greetings hetral
