Hi everyone,

I'm experiencing a persistent issue where my Docker tab in the Unraid GUI hangs indefinitely on "Please wait..." and any attempt to pull a new image results in a "context deadline exceeded" or "request canceled while waiting for connection" error.

What happened: The issue started after a crash of a VPN container (Gluetun/Netbird). Since then, the Docker service seems to be in a deadlock.

Symptoms:

• The Docker UI tab never finishes loading.

• Pulling images consistently fails with timeouts.

• nslookup inside the terminal shows timeouts for standard lookups, seemingly attempting to route through a leftover Tailscale/VPN interface (100.100.100.100).

• I have already tried restarting the Docker service and pruning networks, but the issue persists after reboots.

• The docker.img has not been deleted to preserve data.

What I have tried:

• Verified network DNS settings (1.1.1.1/8.8.8.8) in the GUI, but the system still seems to attempt routing via the old VPN/Tailscale interface.

• Checked iptables and network interfaces, but unable to clear the deadlock.

• The logs show that the Docker daemon is struggling to connect to registry-1.docker.io.

I have attached my diagnostics file to this post. Could you please help me identify which zombie process or network interface is blocking the Docker daemon?

I want to avoid deleting the docker image/rebuilding everything if possible.

Thank you for your help!

I would start by recreating the Docker image in case there is one or more stale networks present

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#re-creating-the-docker-image-file

Then:

Also see below if you have any custom docker networks:

cant create docker container because they dont exist localy and i got no connection to the server to pull the images but i got my problem solved i guess

every time i tryed to pull a docker that happens :nslookup registry-1.docker.io

;; communications error to 100.122.xxx.xxx#53: connection refused

;; communications error to 100.122.xxx.xxx#53: connection refused

;; communications error to 100.122.xxx.xxx#53: connection refused

;; no servers could be reached

that was a Tailscale IP

solved :
kill TS & Netbird Plugin

killall -HUP dnsmasq

echo "nameserver 8.8.8.8" > /etc/resolv.conf

echo "nameserver 1.1.1.1" >> /etc/resolv.conf

/etc/rc.d/rc.docker restart

nslookup registry-1.docker.io

Server: 8.8.8.8

Address: 8.8.8.8#53

after that it works fine i got all my containers from recreate back without great issues exept nextcloud but i got this really fast fixed cuz my custom network was deleted aswell for nextcloud
