Hmm. So I took the easy way yesterday and removed the netmaker install instead of upgrading to 0.13.0. I installed using the nm-quick script, and didn't specify domain, thus using the nm-.nip.io domain. Everything worked fine so I wiped again (docker-compose down -v --rmi all) and ran nm-quick again but with my domain (using cloudflare (*.netmaker.mydomain.com) which points to the public IP of the netmaker server). All seemed fine, but when nodes try to join it just hangs during the process. comparing the docker logs for caddy between my domain and the nm.nip.io domain, I can see that

{"level":"info","ts":1651089317.0613978,"logger":"tls.obtain","msg":"acquiring lock","identifier":"api.nm.<ip>.nip.io"}

never shows up when using my domain. Am I missing some setting or similar? :/
