Errors about getaddrinfo and reading undefined for random containers at each run

[tapufd]

Hi,
Lately I notice that WUD frequently lists containers that are so-to-say not up-to-date, although they are already.
I think it is related with the following errors I see from the WUD container:

• Error: getaddrinfo EAI_AGAIN auth.docker.io
• Error: getaddrinfo EAI_AGAIN registry-1.docker.io
• Cannot read properties of undefined (reading 'tag')
  I get these errors for random containers at almost every check/run.
  I do a check/run every once a week, to not overload docker hub.
  Any idea what this is about?
  Br, T

I have the same issue, the container is unable to make outbound DNS/HTTP requests.

Ubuntu 22.04.4 LTS running Docker version 26.1.0, build 9714adc

I have 10+ containers on the same docker network and they can all access the Internet without issue, only this container (and wallabag) have this issue.

/etc/resolf.conf is the same for both a working container and the wud container

Not sure if something is hard coded during the build causing this?
