Hi all, I have recently managed to get an installation of OOD going on my hpc. I have added a desktop app by cloning the “bc_desktop” repo here . The desktop app successfully launches but I get a “Failed to connect to server” on the noVNC page. The output.log is below: Setting VNC password... Start…

[image] badamifs: rnode_uri: 'rnode' You’re rnode_uri here needs to be /rnode (it’s missing the first backslash).

These 2 errors stick out to me. First you can’t seem to find websockify. And secondly your XDG_RUNTIME_DIR doesn’t seem to be valid. /var/spool/slurmd/job31383/slurm_script: line 193: /usr/bin/websockify: No such file or directory dbus[178581]: Unable to set up transient service directory: XDG_RUN…

Thank you for the quick response. I was able to correct the websockify error. For the XDG error: dbus[76297]: Unable to set up transient service directory: XDG_RUNTIME_DIR "/run/user/1001" not available: No such file or directory I added the recommended export command to the submit.yml.erb under /…

Can you share the yml file? There seems to be a syntax error with your YAML.

Here you go. hpc_altoneuro.yml (343 Bytes) submit.yml (84 Bytes)

You’re missing the before_script section, it should look like this. --- batch_connect: template: vnc before_script: | export XDG_RUNTIME_DIR="$TMPDIR/xdg_runtime" Also note that you can set these options globally by cluster so they’ll work for all apps for that given cluster. https://osc.…

Got it and will set it globally after testing. So I had to manually make a /tmp/xdg_runtime directory for the error to go away (of course after making the change you recommended). Not sure if thats the right thing to do here? Both the websockify and XDG errors dont show up in the output.log anymor…

Looks that it’s booting OK. What’s the experience you’re seeing on the client side? I mean - what’s the error you’re seeing in your browser?

The same failed to connect to server message. Screenshot attached: [Screen Shot 2022-10-05 at 1.31.33 PM]

You do not have SSL on your apache server? I think that could be it. I believe that the vnc library here is requiring a secure connection. Do you have any error messages out of your browsers console? (open developer tools with F12 and navigate to the console tab)

No SSL yet. Whenever I’ve tried to add the ssl cert and key to my ood_portal I have not been able to get httpd to restart. See the ood portal above lines 32, 33 and 34 once uncommented dont let httpd restart. The cert and key are from where the domain is registered. Any advice on how to get https go…
