Websockify fails to establish connection

I was sure I had this working before. Starting a shell under Clusters->Tempest Shell Access works fine (which opens ssh to the login-node), but when I create an interactive job the link to open a shell on the compute node gives me:

Failed to establish a websocket connection. Be sure you are using a browser that supports websocket connections.

I’m using Chrome Version 106.0.5249.119 (Official Build) (64-bit). I have reverse DNS working fine. I can’t seem to find any kind of log to tell me what’s going on. Websockify is installed on the compute node I’m working on in python3.6.

I appreciate any thoughts :slight_smile:

Are you able to open the dev tools with f12 and look at the request headers when it’s made to see if a response is in fact coming back? Seeing a screen shot of that would be helpful since no logs are indicating anything.

Also, are you behind any kind of load balancer?

Hi Travis!
My issue was I had not specifically set up OOD_SSHHOST_ALLOWLIST in /etc/ood/config/apps/shell/env. Once I added that it worked like a charm :slight_smile:

Thanks for your response!
