hi,

does it work from a different browser? (you can try in incognito mode)

I also have the same problem in chromium based browsers (google, vivaldi, opera).

 

[oguz]

can you provide more details?
accessing novnc with chromium based browser works here on the latest versions.

please tell us your:
* pveversion -v
* chromium version

also did you customize your /etc/ssh/sshd_config file? does it have this line:

AcceptEnv LANG LC_*

in it?

Plus the directive

SendEnv LC_PVE_TICKET

in /etc/ssh/ssh_config if you hardened the ssh client as well.
