WebSocket error

[manuelmeurer]

I'm trying to get the debugbar up and running, but I keep getting the "WebSocket connection to 'ws://127.0.0.1:3000/_debugbar/cable' failed:" error...
I'm using a Rails 8 app and puma-dev.

What I've tried:

• replacing 127.0.0.1 with localhost (debugbar_body cable: { url: "ws://localhost:3000" })
• using the async adapter or solid_queue in dev
• adding config.action_cable.disable_request_forgery_protection = true to config/environments/development.rb

Any other ideas?

I use Puma in single mode.
