I installed on a Raspberry Pi 3 with Jessi Lite Gitlab Ce (https://about.gitlab.com/downloads/#raspberrypi2), in local network everything works fine. But i can only open GitlabCe with the local ip from Raspberry Pi. I try to connect to GitlabCe over the Internet using http/https, when i try to generate a letsencrypt Certifikate i get the following error:
Failed authorization procedure. gitlab-comeet.de (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: NXDOMAIN looking up A for gitlab-comeet.de, www.gitlab-comeet.de (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: NXDOMAIN looking up A for www.gitlab-comeet.de
The following errors were reported by the server:
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
I have no Idea what the problem is, tryed a hole bunch of domain but nothing seems to be working. I opend Port 80 and 443 to the RaspberryPi local IP.
