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

Hello everyone
This is a Bug

Well I will tell you what is happening in the version of Zentyal 6.2, I think it may be related to a bug in the Virtualization module, which occurs when any service certificate is configured in the CA module.

Try to access the web console of the VM, when it returns the error 'code: 1006', check in the log file if the registry exists:

Code: [Select]
[X509: KEY_VALUES_MISMATCH] key values mismatch
To verify it you can run the following command:

Code: [Select]
grep '\[X509: KEY_VALUES_MISMATCH\] key values mismatch' /var/log/syslog
If you find the bug, please write.

I don't write anymore, because I don't know what is required.

Since my first ticket for Let's Encrypt support: https://github.com/zentyal/zentyal/issues/1836 (it has been closed by Zentyal Team).

I have created a second ticket for Let's Encrypt support which has been closed by Zentyal Team too.

I have created a third ticket for Let's Encrypt support, can you like, comment on it?
