Original GitHub issue: https://github.com/fosrl/pangolin/issues/2364

Describe the Bug

When opening the "Request Logs" section the following error appears in the traefik logs:
ERR Provider error, retrying in 586.330963ms error="cannot fetch configuration data: do fetch request: Get \"http://pangolin-app:3001/api/v1/traefik-config\": context deadline exceeded (Client.Timeout exceeded while awaiting headers)" providerName=http
When the error appears in the logs the Dashboard also spits out a Modal that states: "Error: failed to filter logs"

On one of my larger instances the "Request Logs" page never loads and ends up locking up the dashboard for a time.

Environment

  • OS Type & Version: Almalinux 9.7
  • Pangolin Version: 1.15.1
  • Gerbil Version: 1.3.0
  • Traefik Version: 3.6.7
  • Newt Version: 1.9.0
  • Olm Version: (if applicable)
  • Container Runtime: podman 5.6.0

To Reproduce

Open "Request Logs" section

Expected Behavior

Request Logs appear without error

I was able to fix this issues in my specific setup by ... requesting RAM increase for Pangolin's VM from 1 Gb to 2 Gb. May be be Pangolin just OOMs?

Same as @intari
I upgraded the RAM to 2GB and the issue has been resolved.

@ErroneousBosch I also didn't limit resources in docker-compose, only hypervisor limits in hosting's admin panel.

Not for me. My server has 4 GB available and never peaks past 2 GB.

I restarted my stack with port 3001 on the Pangolin container exposed. we'll see if it makes a difference. usually for internal docker network calls like these you don't need it

@m-elsharkawi commented on GitHub (Apr 13, 2026):

I found what was causing a similar issue for me. Docker bridge networking on the host was broken by stale nftables raw PREROUTING rules left behind after the outage and network recreation.

Symptoms were:

  • host -> container worked
  • container name resolution worked
  • but container -> container traffic on the same Docker bridge timed out

In my case, pangolin and gerbil were on the same bridge, but nft list ruleset showed old rules like these still dropping traffic:

ip daddr 172.18.0.2 iifname != "docker_gwbridge" drop
ip daddr 172.18.0.3 iifname != "docker_gwbridge" drop

Those rules were stale and no longer matched the current bridge.

What fixed it:

  1. Inspect the nftables raw rules:
sudo nft -a list chain ip raw PREROUTING

  1. Identify the stale drop rules for the affected container IPs.

  2. Delete the bad rules by handle:

sudo nft delete rule ip raw PREROUTING handle <handle>

In my case, removing the stale rules immediately restored container-to-container connectivity and Pangolin started working again.

A Docker restart alone did not remove those stale rules, so checking nft directly was the key.
