Description

I could use some help in exposing resources from another server using Pangolin.

My Setup

I have multiple machines on my local network running various services that I want to expose using Pangolin.

Installed LXC on my Proxmox server, which has access to all of these services.
Inside the LXC, I installed Docker and set up Newt.
The Newt instance is online and visible on my Pangolin server.
Pangolin is hosted on a VPS outside my local network.

What I Did

I attempted to expose an HTTPS resource.
I specified a URL that is accessible from within the LXC.
However, when I visit the URL provided by Pangolin, I only see a 404 error.

My Network Setup (Simplified)

Local Network Setup:
- Router with local DNS that resolves *.machine-01.home.domain.com to the IP of machine-01.
- machine-01 runs Docker containers (e.g., Traefik-managed services):
  - Example: hello-world.machine-01.home.domain.com
Proxmox Setup:
- Proxmox (machine-02) has an LXC that can access hello-world.machine-01.home.domain.com without issues.
- Newt is running in Docker inside the LXC on Proxmox.
Pangolin Setup:
- Pangolin is running on VPS (pangolin.remote-01.not-home.domain.com).

The Issue

I added the resource via Pangolin, expecting to access:

https://hello-world.remote-01.not-home.domain.com

However, I only get a 404 error.

Debugging Attempts

Checked Traefik logs and Pangolin logs but did not find anything helpful.

Question

How can I properly debug this issue?
What could I be doing wrong in my setup?

Any help would be greatly appreciated!
