Suddenly "Error - IP" on both Port 80 and 443 checks in lxc container and no connection to nextcloud

new day new tests.

I followed the guide to setup a new lxc container based on this

ofc i ran the wizard and activated the new instance. Here i deffered from the guide and used the public ip of the host and not the container, but the activation dialogue opened nevertheless.

also available from “outside”

turns out i can acces the nc instance now from inside and outside of my network (still getting complaints about wrong certificates but yeah…) also after activation

however getting letsencrypt to go fails. also still not able to ping the outside world from inside the host, and also the same behavior in ncp-config (waiting for new version answer from the big big internet and noone answers…)

So… what could be the reason?

I investigated further and setup a new bridge network and relaunched the container. That yielded precisely the same results.

New ideas?
