I’m new to Tailscale and I’m running into an issue where dns inside docker containers stops working which breaks functionality.
I have a bunch of docker containers setup and working fine for months. I then recently installed Tailscale on the host machine. I setup Tailscale to use NextDNS and on that Debian machine I setup Tailscale to be a exit node.
After a few hours I noticed some of the apps I have running in docker stopped working. Digging around a little bit I discovered that dns no longer works inside the containers. Stopping Tailscale and restarting the containers fixes the issue.
My networking skills are limited and I have no idea what causes this or how I can fix it. Any suggestions?
