imer told me he is back on sunday, when I asked him abotu a different forum problem, I added a PM to that conversation about the HTTPs problem yesterday
Apparently the ipv6 config of the vm stopped working, so it would fail to contact letsencrypt to renew the certificate
It's working again now (for some reason, no clue why this config works now cause i tried it before and it didnt) + I set it to prefer ipv4 over ipv6 for connections
