docker sets up some iptables rules, borks everything, in the name of security i believe.
info i used to solve:
https://docs.docker.com/network/packet-filtering-firewalls/#docker-on-a-router...
sudo systemctl edit docker
add this:
[Service]
ExecStartPost=iptables -I DOCKER-USER -j ACCEPT
save
reboot
probably a huge security risk or wahatever, and not recommended see above. but it works for me
Afaik that is correct, attempting to change the hostname of a host that is set up is not supported, or recommended.
but if you back up your containers and vms, reinstall, and do the steps laid out in the comment above yours, you can restore the containers afterwards no problem.

i fixed it though: i had to stop the container, mount the disk image file in a tmp directory, and remove (container root)/dev/lxc-125.log, which was not present when the container was running.
no change, but I just realized the console in proxmox web interface no longer works for any container however SSH works fine:

as per https://pve.proxmox.com/wiki/IO_Scheduler I tried checking available io schedulers for my drives, they all only specify mq-deadline and none.
