Request to Soketi container hanging - not connecting properly?

Hey, pretty new to Railway containers - I'm trying to trigger a Pusher event, targeting a soketi container that I've got hosted. When I do this, the request is stuck in pending (network dev tools) until it eventually 500s. My application is a nextjs app using trpc hosted on vercel, but i'm currently testing it locally. I've attached: The trpc mutation including the code to trigger the event The pusher object, env file contains the secrets and host is my container address The container variables including a por variable someone suggested I try out The dockerfile for the container The network error When I remove the pusher.trigger call, the mutation works correctly. I assume the issue is that it's not able to communicate. If there's anything else I can show to help please let me know, I'm really stuck on this one.
