My n8n worker node keeps crashing on Railway

[ckmoocow]

Describe the problem/error/question

I have n8n deployed on Railway. It was working fine until I hit my usage limit, and they shut my instance down. Now I can’t seem to get the worker back up without having it crash a few minutes after restarting/redeploying.

What is the error message (if any)?

This could be due to a crash of an active workflow or a restart of n8n.

Hi @ckmoocow,

Did you make any changes to your active workflows since you got the instance back up after it having been shut down?

Have you reached out to Railway about this? Seems mainly to be a deployment issue

[ckmoocow]

I haven’t made any changes. I did contact Railway first, and they said they won’t support 3rd party apps.

This somehow sounds like a permissions issue?

I’m not able to see those Railway links, can you please share the deploy logs through elsewhere? Can you copy paste them into a code block in here?

Thanks

The timestamps don’t really link to much more info:

I have the same issue…

We don’t officially support Railway but looking at that error I suspect the issue is likely to be with the connection to the Redis instance, Can you make sure you have the environment options correctly set
