I always get the error message shown below when requesting a certificate. According to letsdebug.net everything is configured and ok. Nevertheless it doesn’t work.
Can somebody help me out?
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: hydra.local.home.goroot.de
I ran this command: docker traefik restart
It produced this output:
