Originally created by @migandhi on GitHub (Apr 20, 2025).

Hi,

I have a website
That was working fine with ngrok tunneling ngrok http 8080
It is locally hosted
But when I use it as pangolin resource

I get "internal server error"

And one other streaming application also
was working good with ngrok http 8050

But it results in error while using pangolin,
like "error loading video"

Why I cannot get a high quality connection in comparison?

Regards.

@migandhi commented on GitHub (Apr 20, 2025):

This problem is related to https,
when I removed https from target resource, I resolved the issues ,
I should only create http target resource
Why?

Also I hope there would be no further issues.

I am also curious how to make a TCP target resource,
for example hosting game server, or communication server on a port
using TCP protocol instead of http

I also saw the h2c option , what is it?

So far I think this is a very useful project
I like it very much
Hope these are only minor issues.

Thanks,
Regards.

Joining this as I had the same experience. Why does only http work? Seems insecure but I also enabled SSL (https) sooo?

I have a similar problem.

I also get an “Internal Server Error” although everything is set correctly.

I can reach the website from the container with traefik and garbil via the wireguard ip + port, but when I do the route set with traefik and pangolin, I don't get the website but the “Internal Server Error”.

EDIT:
I don't know what the problem was but I reinstalled the pangolin once and now it works

This could be related to the internal_hostname set in the config. The other containers in the stack need to be able to address Pangolin internally by that hostname. We've seen this cause Internal Server Error for others.

Glad you were able to get it working!

that could have been the problem “internal_hostname” was previously set to ‘localhost’ and then changed it to “pangolin” during the new installation

pelican-panel/wings is based on pterodactly/wings. The only difference is the design.
wings and pangolin must be in the same network in Docker and the container_name of pangolin must be the same as the internal_hostname of the configuration of pangolin.

docker-compose.yml:

services:
  pangolin:
    image: fosrl/pangolin:1.4.0
    container_name: pangolin
    restart: unless-stopped
    volumes:
      - /opt/pangolin:/app/config
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:3001/api/v1/"]
      interval: "3s"
      timeout: "3s"
      retries: 15

  gerbil:
    image: fosrl/gerbil:1.0.0
    container_name: gerbil
    restart: unless-stopped
    depends_on:
      pangolin:
        condition: service_healthy
    #entrypoint: ["/var/config/start.sh"]
    command:
      - --reachableAt=http://gerbil:3003
      - --generateAndSaveKeyTo=/var/config/key
      - --remoteConfig=http://pangolin:3001/api/v1/gerbil/get-config
      - --reportBandwidthTo=http://pangolin:3001/api/v1/gerbil/receive-bandwidth
    volumes:
      - /opt/pangolin:/var/config
    dns: 1.1.1.1
    cap_add:
      - NET_ADMIN
      - SYS_MODULE
    ports:
      - 51820:51820/udp
      - 443:443
      - 80:80
      # ALL GAME PORTS YOUR A USED
      - 2022:2022 # WINGS SFTP PORT

  traefik:
    image: traefik:v3.3.3
    container_name: traefik
    restart: unless-stopped
    network_mode: service:gerbil
    depends_on:
      pangolin:
        condition: service_healthy
    command:
      - --configFile=/etc/traefik/traefik_config.yml
    volumes:
      - /opt/pangolin/traefik:/etc/traefik:ro
      - /opt/pangolin/letsencrypt:/letsencrypt

  wings:
    ...
    network_mode: service:gerbil
    # REMOVE ALL PORTS

  panel:
    ...
    networks:
      - default
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.panel.rule=Host(`panel.yourdomain.com`)"
      - "traefik.http.routers.panel.tls=true"
      - "traefik.http.routers.panel.tls.certresolver=resolver"
      - "traefik.http.services.panel.loadbalancer.server.port=443"

networks:
  default:
    driver: bridge
    name: pangolin

pangolin config.yml

...
server:
  ...
  internal_hostname: "pangolin"
  ...
...

for example but not testet
