Not Compatible with Nginx Proxy Manager?

Environment I am looking to utilize NetMaker on my homelab that is running Proxmox on a LXC container. I have a Nginx Proxy Manager LXC setup that is forwarding the required sub-domains to the LXC hosting NetMaker, including API.{NM_DOMAIN}, Dashboard.{NM_DOMAIN}, grpc.{NM_DOMAIN}, and broker.{NM_DOMAIN}.

Issue Description When I install NetMaker utilizing the quick installer provided, I receive the following

Expected Outcome

I would expect for NetMaker to install successfully.

Does anyone have any recommendations of what I can try? I have spent hours diagnosing this issue and have not had any luck.

I have tried using the community docker-compose script to run without Caddy, and that also did not work for me. Whenever I try accessing dashboard, I reach the 502 openresty page.

I know my proxy manager itself is working correctly, because traffic will forward to other LXCs I am running. I'm assuming this may have something to do with headers, but I am not nearly experienced enough with Nginx or Caddy to track down the issue.

Any recommendations would be greatly appreciated!
