Hello,

I'm sorry but i need help for that error. I tried to resolv it but i cannot manage to make it work.

4 VMs, access via web gui, ssh, http/s, are ok. Except NoVnc. So i clear browser cache ...

First i check my fw but in it i use a "management" IpSet, i allow everything from my fixed ip, and i add 5900-6200 ports (i know it is better to be safe than sorry... nothing work. [In french : to wears both a belt and suspenders.]
Second I tried to reinstall defaults certs via "pvecm updatecerts -f" after mv the actuals one, reboot the node (a friday before lunch...), does not work.

Try from another computer, does not work either.

Firefox ne peut établir de connexion avec le serveur à l’adresse wss://91.121.9.01/api2/json/nodes/ns3050785/qemu/100/vncwebsocket?port=5900&vncticket=PVEVNC%3A5C5 ..... even with explicitly open ports.

So here i am and i dont know where to look now. If anybody have a idea for me, thanks.

Rémy
