Virtual pc console from the management page not open

Hi!

My great pleasure with the zentyal 6 is the possibility of virtualization.
I think this was a very good decision.

But I had a problem with it because unfortunately something went wrong during the updates. After the current zentyal updates, the virtual pc console will not open:
- I get this error message on my website: Server disconnected (code: 1006)
- log in: 201/12/12 09:13:42 [error] 3825 # 3825: * 328 peer closed connection in SSL handshake (104: Connection reset by peer) client: 192.168.100.27 , server:, request: "GET / websockify? token = praxis-pc-32bit-en HTTP / 1.1", upstream: "https://127.0.0.1:6900/?token=praxis-pc-32bit-hu", host: "192.168.100.10:8443"

The vnc reaches 5900 port-free.
The console was also flawless before upgrading.

Has anyone ever encountered such a mistake?

Hi All!

I have been found the main problem:
CERT issue, the system is using old self signed cert what is not usable....
I modify the zentyal.vncproxy.service config under /lib/systemd/system/
I use a letsencrypt cert.What is perfectly worked for me.

This problem is solved too. :-)

PS: this modification is not to nice, if somebody can help me to found a better solution...

Hi Gabor!

Thank you for explaining your fix. I wonder why this issue with the self signed certificate.  :P

Cheers!

Hello,

I ran into the same issue - I had to change/update my certification authority, since then the Console of VM does not open any longer.
The VM is running an d can be accessed from "outside" via e.g. putty.

Is there something like "cleanup" certificates/ssl/cache or else?

THX & BR
