Need help with PubSub Example

Hi! Im trying to develop a panel extension. I am using Node with Developer Rig.

I have imorted the PubSUb template and the frontend at least works in dev rig.

I’ve setted the same Uri in dev extension console than the one that the backend shows.

I’ve run “node bin/generate_cert.js server”, so i have the conf folder with certificates inside,

but i have 404 GET problem.
can anyone help me?

thank you!
