I apologize for lacking the clarification needed.
I’m using a reverse proxy to route the IP address 192.168.1.XXX to a subdomain i.e. discourse.mydomain.com, so in-short yes, it’s on-prem.
It’s currently inaccessible via LAN or WAN (mobile)
after running sudo netstat -tlnp | grep LISTEN I see the ports 89 and 449 listed, but traveling to the local ip e.g. 192.168.1.XXX:449 (or 89) doesn’t work.
And of course the reverse proxy (from the Synology NAS) doesn’t help, so the subdomain I’ve configured is a dead end.
For total clarification, the machine I’m attempting to host Discourse on is a VM hosted on a machine with XCPNG. The VM OS is the latest Ubuntu Server (CLIN)
