hello, any suggestion?

please try and post the output of:
Code: 
apt update
apt full-upgrade

if this does not help:
* start following the journal in a shell - `journalctl -f`
* log-in to the node and reproduce the error
* post the output of the journal from the start until the error shows up
 
thank you, kindly see below:

Hmm - it's odd - and I could not reproduce the issue...

on a hunch:
* try restarting pveproxy and pvedaemon

* could you check the developer console of your browser - and see if it shows any issues?
* if not - could you please show which request your browser is sending exactly?
* add to that the request line from /var/log/pveproxy/access.log

* do you have any manual modification to the code? (GUI or backend?)
 
i did tried restart the host few times.

editing the VM will cause this error to appear when trying to click OK.

again /var/log/pveproxy/access.log does not have any log output from that error.

i am afraid i might had did some edit on the GUI or Backend, is there anyway that i can reinstall just the Backend and GUI without touching the VM configuration?

thank you.

try reinstalling:
* libpve-common-perl
* pve-manager
* qemu-server
`apt install --reinstall libpve-common-perl pve-manager qemu-server`

if this does not help - try the reinstallation with all packages listed with `pveversion -v`
