✅ Have you read and understood the above guidelines?

yes

🔎 Did you run the script with verbose mode enabled?

Yes, verbose mode was enabled and the output is included below

📜 What is the name of the script you are using?

Pangolin

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/pangolin.sh)"

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 13

📈 Which Proxmox version are you on?

pve-manager/9.1.1/42db4a6cf33dac83 (running kernel: 6.17.2-1-pve)

📝 Provide a clear and concise description of the issue.

The pangolin install script hardcodes Traefik's badger plugin's version. Traefik uses strict version check. Which causes a mismatch b/w the actual plugin version installed vs what is mentioned in the traefik's config file causing a middleware failure and thereby causing reverse proxy of public resources to not work.

🔄 Steps to reproduce the issue.

  • Install Pangolin

  • Setup a local-only site

  • Add a public resource using the site and point to the instance where the service is hosted

  • try to access the service

  • notice that reverse proxy does not work and throws a 404 error.

  • goto http://<container_ip>:8080 to access Traefik WebUI

  • Notice the error in routing

❌ Paste the full error output (if available).

invalid middleware "badger@http" configuration:
invalid middleware
type or middleware does not exist

🖼️ Additional context (optional).

Changing badger version to currently latest v1.3.1 in /opt/pangolin/config/traefik/traefik_config.yml fixes the issue

This is the culprit: f3be88ad98/install/pangolin-install.sh (L84-L90)

version should not be hardcoded, I believe the update script might have the same issue. I didn't check it though
