Difficult debugging problem

Yes its always the same domains. Ok, I will re-enable those for sure then.

Here is my Dockerfile (i’m just putting it anyway just in case it helps debugging). Thanks, good point. Maybe I can just add a temporary line where I add apk --no-cache --update add net-tools iproute2 and comment it out when I’m not using it
