Missing port on the connect URL to vnc sessions

Get Help

Hi all,
First all, thanks for this amazing tool (Open Ondemand) that really helps a lot of institutions ww.

Now, I need some help to complete the set up of the vnc/desktop app in our institution.

We have now the app install and close to be working complete.
The jobs are sent to slurm, the Xvnc sessions are open on the compute nodes, and the protal detects properly that the session is available.

But when we click the button “Launch Desktop” , we get the page with the vnc webclient but it does not reach the session in the node.

Looking to the url use, looks like the port is missing and just adding the port between the remote hostname and the websockify , it works

The connection.yml file looks good (I think), for example

host: (correct hostname)
port: 5901
password: cKHzlH47
display: 1
websocket: 61344
spassword: O88gCFdg

any help here is more than welcome about what is missing in terms of config and suggested changes

Cheers
Roberto

OK - that’s odd that it’s not populating the port here. Can you share the output.log?

To be clear - you indicate you edited the connection.yml directly and it started to work? Or you edited the url and it started to work?

Hi Jeff,
Apologies for the long delay on the reply

I edited the URL not the connection.yml file. The connection.yml looks good from the beginning.

Here you have the output.log

Here’s a relevant line. Do you have websockify installed and OOD configured to look at the correct binary?
