[SOLVED] Can't edit any resources via GUI since the last update. Why?

[Thalix]

As you can clearly see, the server is online. Why do I get this message?

Hi,

Did you reboot PVE node after upgrade? - if not, please try to reboot it.

did you see any error in journalctl or syslog?

 

[Thalix]

Yes I have rebooted the node. I only see one error in all log files:

Oct 16 10:56:58 titan kernel: [42812.257322] audit: type=1400 audit(1602838618.092:524): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxc-500_</var/lib/lxc>" name="/run/systemd/unit-root/" pid=55324 comm="(resolved)" srcname="/" flags="rw, rbind"

But the problem occurs on all VM and LXC containers, not only on container 500.

EDIT: I fixed the apparmor error with adding features: nesting=1. But the initial problem still exists!

Found it. We had a hardening on our nginx reverse proxy that got activated with the last reboot.
This is the cause:

add_header Allow "GET, POST, HEAD" always;
if ( $request_method !~ ^(GET|POST|HEAD)$ ) { return 444; }

May I ask what additional HTTP method we need to include? Thanks!
