Describe the problem/error/question

I’m trying to run an advanced n8n automation (deep researcher template by Jim Leuk), but it won’t work for me. it keeps sending me to this url when it tries to ask me follow up questions:

http://localhost:5678/form-waiting/36475

I self hosted on railway using the most used template. so not sure what the issue is?

What is the error message (if any)?

It just hangs. and can’t continue, because it’s waiting for an answer from me, but i can’t get access to the form.

Is your workflow active? Sometimes it’s important to activate the workflow to make some webhooks work.

Hey @Hanson_Cheng,

That “localhost:5678” link indicates n8n is generating URLs for a local server instead of the live Railway deployment. You need to configure n8n so it knows its public address.

Set the environment variable WEBHOOK_TUNNEL_URL (or N8N_HOST / N8N_ENDPOINT_WEBHOOK depending on your setup) to your public Railway URL.

Then restart n8n so these settings take effect.

Do you know how to do that? Maybe ChatGPT can guide you a bit and if it’s still confusing, ask for more help.

I’m also gonna ping other supporters to make sure you keep receiving help.
