Hi more experts than me, I run into this shit an hour ago and cannot capacitate what happened but it is reproducible.
On my Demo Proxmox server i have installed the MeTube LXC, worked perfectly until I tried to set the DNS domain as in
the pic. below to api.cloudflare.com

Since that change the site video.xxxx.org is opening this Zyxel Firewall instead od the MeTube page.

Problem is I changed the DNS domain setting back to normal, rebooted the LXC, all remained the same, than rebooted Proxmox: no chenge always getting the Zyxel USG login page as it were a virus.
Can anyone tell what happened and howto revert this setting ?
Thanks in advance, Pax
