Additional context

Something is wrong with the dns server.

Can you explain how did you install invidious?

[HaJue60]

Hello Unixfox,
thank you for the fast anser.
I installed it as descibed in https://docs.invidious.io/installation/#docker-compose-method-production
it is a fresh installation.

nslookup www.youtube.com on server is working. see attachment
nslookup_on_raspi.txt

inside the container I got an error:
/invidious $ nslookup www.youtube.com
;; connection timed out; no servers could be reached

/invidious $

So you it seems that you are right, but at the moment I have no idea why the docker container connot find the dns-server

What's the architecture of your RPI? Is it ARMv8 or ARM64? You can find it in uname -a.

By the way on RPI you should use the correct docker image: #361 (comment)

maybe important:
I've running a pihole in the same docker environment.

[HaJue60]

I found a workaround:
I've changed the docker-compose.yml of the pihole as desribed in

https://discourse.pi-hole.net/t/solve-dns-resolution-in-other-containers-when-using-docker-pihole/31413

now it is working

I'll close this issue as it was a misconfiguration on your side.
