AdGuard on Docker fails to restart

[uncovery]

I am trying to install AdGuard Home as a docker image on a QNAP Container station.
It works fine to install it and then run it, but it fails to stop and re-start the docker image due to the following error:

[fatal] couldn't start forwarding DNS server: couldn't listen to UDP socket, cause: listen udp 192.168.1.91:53: bind: cannot assign requested address

Prerequisites

• I am running the latest version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Issue Details

• Version of AdGuard Home server:
  • Latest Docker image, v0.104.3
• How did you setup DNS configuration:
  • Router DHCP
• If it's a router or IoT, please write device model:
  • LinkSys Velop
• Operating system and version:
  • QNAP QTS (latest)

Screenshots

Here is the docker terminal log on restart:

Tbh, I have no idea what could be causing this:(

[uncovery]

fair enough, if you want, close it. I gave up on the docker now and moved it to a virtual machine again. Or leave it open in case someone else has the same issue.

[ameshkov]

Well, let's keep it open for some time until stale bot closes it

[J0han3s]

Any idea on this - i have the same issue?

[rtp8725]

Same issue here. For some reason the suggested troubleshooting article of modifying resolved daemon for docker won’t work on qnap because they don’t use systemd or the resolve daemon they use some other driver or whatever they call it ( still learning Linux systems). However one solution is to use bridge networking where docker container has it own MAC address and thereby it’s own lan ip therefore able to bind on the port .. sadly have t yet been able to get an ipv6 address for the docker container

Hey, I had the same problem and I found a solution.
Adguard configuration file has "dns.bind_hosts". In this block adguard writes its ip (internal ip from docker network).
So, if IP has changed, this error will appear.
I've set ip to 0.0.0.0 and it started working without any problems!
