Which version of noVNC are you using?

What does the browser console say?

AntoWkill commented 7 years ago
novnc1 novnc2 novnc3 novnc4

VERSION: novnc-pve: 0.5-9 (on proxmox)

CendioOssman commented 7 years ago

That is very old. I would suggest testing master.

However the logs seem to indicate a normal disconnect from the server. What VNC server is this? Can you check its log files?

AntoWkill commented 7 years ago

set 25 12:52:29 problem with client XXXX; ssl3_read_bytes: sslv3 alert bad certificate I've already tried both letsencrypt and with the self-signed certificate s(the error becomes sslv3 alert unknown ca)

CendioOssman commented 7 years ago

A bad certificate would not cause the issues you describe. What else does the log say?

AntoWkill commented 7 years ago

Nothing alse on the log, the certificate is no bad Is perfectly working.

AntoWkill commented 7 years ago

I had also tried to use the last version of novnc, and error is the same.

What VNC server are you using?

AntoWkill commented 7 years ago

I think vncterm

CendioOssman commented 7 years ago

That seems to use libvncserver. Are you connecting directly to it, or do you have a websocket proxy inbetween?

AntoWkill commented 7 years ago

Yes there is pveproxy

CendioOssman commented 7 years ago

Alright, so I guess the log is from pveproxy? What does the log from vncterm say?

I found the problem but i haven't solution. The VNC Console start again to work IF i force SSLV3 (insicure). So the problem is tls.

DirectXMan12 commented 7 years ago

hmm... maybe the TLS implementation is mismatched?

AntoWkill commented 7 years ago

And how i can check / solve?

CendioOssman commented 7 years ago

I'm afraid that would be a question for pveproxy. noVNC isn't involved in the TLS stuff in this case, only the browser and pveproxy. So I would suggest your next step would be to file a bug with pveproxy.

I'm going to close this issue since it doesn't involve noVNC.
