Hi,

Can you share the error?

Additionally, have you read this page: https://docs.railway.com/reference/errors/enotfound-redis-railway-internal

I am moving code that has been working on kubernetes, so whatever it is has to got to be something with how I'm setting the environment variables. My connection string seems right:

Can you just make sure you have ?family=0 at the end of your Redis URL? It can cause a bunch of issues with ioredis if you don't.

Ok, I am trying now to connect on my local machine, to the hosted redis via public url:

2025-11-05 10:10:04 [info]: connecting to redis at: redis://default:password@tramway.proxy.rlwy.net:29530?family=0

2025-11-05 10:10:05 [info]: redis connection ready

2025-11-05 10:11:36 [error]: Killing application due to bad startup; Connection is closed. {}

Can you please add more logging to your application and have it display the actual error?

Also, I notice you're using the proxy IP, when you should be using an internal IP.

I'm trying to at least get my local machine running the app connected to the redis so I can debug what's going, I can't use the internal IP for that can I?

Error: Connection is closed.

at processTicksAndRejections (node:internal/process/task_queues:77:11) is all I get

ahh I've found out that it's actually this that's causing the crash, not my normal redis connection I thought it was....

}

its something with how: import CatboxRedis from '@hapi/catbox-redis' tries to connect

Well, I've gone ahead and removed catbox, this was an unneccasary optimization
