Please check help me!

Im use noVNC lib

what do you mean by that? are you trying to implement a custom novnc client? if yes, what did you do exactly?

Having about the same problem here. I get a session from the endpoint:

'/nodes/' . $master->node . '/qemu/' . $server->vmid . '/vncproxy'

Afterwards I open the websocket hitting the following endpoint:

'/nodes/' . $master->node . '/qemu/' . $server->vmid . '/vncwebsocket'

Seems to work like a charm. I get a ticket and the socket is supposedly opened. I then try to connect to the websocket as follows:

wss://[PROXMOX_URL]:8006/api2/json/nodes/[NODE]/qemu/[VMID]/vncwebsocket?port=5902&vncticket=[URLENCODED_VNC_TICKET]

Now that ends up in the same "HTTP authentication failed" message as @hntloveit showed above. I'm using an external noVNC HTML5 client with the following URL parameters (settings) set:

vnc.html?autoconnect=1&reconnect=1&logging=debug&host=[PVE_HOST]&password=[URLENCODED_VNC_TICKET]&path=api2%2Fjson%2Fnodes%2F[PVE_NODE]%2Fqemu%2F61338%2Fvncwebsocket%3Fport%3D5901%26vncticket%3D[URLENCODED_VNC_TICKET]

FYI: I see a console session popping up in the Proxmox log, although I can't connect to the websocket. I suppose something's wrong with the parameters provided to noVNC.

I had to set some placeholders to preserve privacy. If anything critical is missing just ask.

Can anyone help solving this?

Thanks in advance!

the connection to the websocket has to carry the proxmox auth ticket as a cookie

Sorry for the late reply but thanks for mentioning @dcsapak. I injected the cookie into the websocket connection and now everything works just fine. It seems like I forgot to set the CORS attributes for the PVEAuthCookie so it wasn't set correctly and therefor not passed to the websocket. Please excuse my own dumbness in this matter.

Kind regards
