Did you open port 3478 UDP and TCP?

still not working, maybe it is something in the talk container, i found that int the container:

[FATAL] [transports/janus_http.c:janus_http_init:795] Couldn't start webserver on port 8088...

I doubt that it is something with the container image itself because it would then have the same problem for everyone...

I think that it may have to do with the caddyfile.

Hello again, did you know which issue or discussion that was, where someone mentioned the same issue with nginx, i think he than improved the config, but i am unable to find that again. I also think it may or may not has to do something with the host, because, OnlyOffice is not working on this Server either, and no it is not because of the os, it has to do something with the Motherboard or something else. Either way, i hope it will work, with the then improved config, and if there are no improvements, i have to dig deeper, why and why not this issue exists.

I know of someone that had also problems with a container image and decided to set up its raspberry pi again. Afterwards it worked...

Sorry that I have no better idea for you...
