Issue Description:

I'm deploying n8n on Railway using the latest setup. Despite following all setup steps and adding the required environment variables, my n8n Webhook node still shows:

CopyEdit

Production URL: https:///webhook/generate-script

—or sometimes—

CopyEdit

Production URL: http://localhost:5678/webhook/generate-script

I'm expecting it to show my public Railway domain like:

CopyEdit

https://n8n-automation-production-xxxxx.up.railway.app/webhook/generate-script

Environment Setup:

I’ve added these environment variables under both Shared Variables and directly in the n8n service:

VariableValueWEBHOOK_URLhttps://${{RAILWAY_PUBLIC_DOMAIN}}/N8N_EDITOR_BASE_URLhttps://${{RAILWAY_PUBLIC_DOMAIN}}/N8N_LISTEN_ADDRESS::PORT5678

I’ve saved and redeployed multiple times, and I’m still not seeing the proper Production URL inside n8n.

What I Need Help With:

• Ensuring the RAILWAY_PUBLIC_DOMAIN resolves correctly in n8n

• Making sure n8n recognizes the environment config and outputs the correct webhook URL

What I’ve Tried:

• Switching webhook node to Production mode

• Activating and saving the workflow

• Redeploying after variable changes

• Logging out/logging in again to n8n

• Creating a new workflow and webhook node
