External Web Interface not connecting with Nginx Proxy Manager in Docker
I have a VPN with Nginx Proxy Manager pointing subdomains to several services to a server that I have at home which is running Portainer. For example, nagios.domain.com reveals the Nagios service on that domain, including SSL from Let’s Encrypt.
I’m having some trouble getting Graylog to work in this fashion externally. The web interface works beautifully internally.
I’ve used example from the Docker Persisting Data docker-compose.yml (Docker — Graylog 4.0.0 documentation). I changed GRAYLOG_HTTP_EXTERNAL_URI=http://127.0.0.1:9000/ to GRAYLOG_HTTP_EXTERNAL_URI=http://192.168.1.83:9000/ and it works. But if I change this to GRAYLOG_HTTP_EXTERNAL_URI=https://graylog.domain.com:9000/ it doesn’t work.
I’ve been able to get the following work internally, but no luck internally:
When I turn off the Let’s Encrypt SSL in Nginx Proxy Manager, I end up getting the generic Apache default page on http://graylog.domain.com.
So I’m a little confused on where to go from here.
