Greetings,
I have tried to install Pangolin on a Racknerd vps with AlmaLinux 8 64 Bit multiple times, with no luck getting it to the dash board....

Following the install instructions and video link on the Fossorial Pangolin github site, the first few times i attempted to install Pangolin it failed to install any docker containers and would not go to the dashboard..The video link showed it installing the docker containers as part of the normal install process..I fixed this issue by installing docker before running the install process for Pangolin..(sudo dnf install docker-ce docker-ce-cli containerd.io docker-compose-plugin)..Finally was able to get Pangolin installed with the docker containers but hit another issue..

Container traefik does not start in pangolin..

Command i run in terminal to try to start docker containers:
(docker compose up -d)

The result in terminal:

✔ Container pangolin Healthy 1.0s
✔ Container gerbil Started 0.0s
⠋ Container traefik Starting 0.0s
Error response from daemon: Container 8fd503fb6f83d39d7bdd8483ca03378543b67eb4ffabc9f93164ca814b5f1b2f is restarting, wait until the container is running.

This traefik container never starts..I also have no access to the dashboard..

Question is:
How do i troubleshoot traefik not starting ??

I see nothing in the var/log/traefik.log

The "A" record and domain have been setup and pointed to the VPS ip address..

Ports 80-443-and 51820 are open in ufw:

Kernel version=4.18.0-513.5.1.el8_9.x86_64..

Traefik version=v3.3.6..

Docker version=26.1.3

1 GB KVM VPS Special Deal - Racknerd VPS
Extra IPv4: None
RAM: 1 GB RAM
CPU Cores: 1 CPU Core
Operating System: AlmaLinux OS 8

Thank you for any troubleshooting help you may have....

....UPDATE....5/24/2025....
As a test I installed Ubuntu 22.04 on the same Racknerd vps server instead of AlmaLinux 8 64 Bit....
I successfully installed Pangolin and was able to reach the dash board....

The sequence i used:
I updated the apt and packages,
Rebooted the Racknerd vps,
Installed ufw,
Opened ports 80 and 443 and 51820,
Installed Docker from this link=https://docs.docker.com/engine/install/ubuntu/
(using the latest version of Docker)
Installed Pangolin from the Github site,
It went right to the dash board with no problem....

Pure speculation, but appears that something in the wireguard area of AlmaLinux 8 64 Bit must be off....
I will continue to look and test....
Thank you....
