N8n run locally docker ngrok does not let me connect google services - timeout

[Estiven]

Hi community! I’ve been trying to connect my Google Drive account to n8n (running via Docker on Linux and ngrok), but I keep getting stuck at the OAuth sign-in step.

Setup details:

• n8n version: 1.102.4

• Deployment: Docker (on Ubuntu Linux)

• Auth: Basic auth enabled

• Public URL (tried):

  • https://(something).ngrok-free.app (via ngrok)

• ENV config:

  N8N_BASIC_AUTH_ACTIVE=true
  N8N_BASIC_AUTH_USER=admin
  N8N_BASIC_AUTH_PASSWORD=***
  N8N_HOST=(something).ngrok-free.app
  N8N_PORT=5678
  N8N_PROTOCOL=https
  WEBHOOK_TUNNEL_URL=https://(something).ngrok-free.app
  NODE_ENV=production
  

Problem:

When I try to authorize my Google Drive credentials, the browser gets stuck or times out at the redirect step with an error like:

“The connection has timed out. The server at (something).ngrok-free.app is taking too long to respond.”

I’ve checked:

• .env file values
• Browser dev tools console (some CSP and 404 warnings)
• checked all trusted urls and forward url in the console.cloud.google, everything is fine
• Firewall (ufw status is inactive)
• curl test gives: Cannot GET /rest/healthz
• Docker logs show no crash; n8n starts fine
• opening n8n with another browser, did not work either

Questions:

• Is there something wrong with my redirect or domain configuration?
• How can I fix the timeout and get OAuth2 working reliably with Google?

Any advice would be hugely appreciated

WEBHOOK_TUNNEL_URL

As of version 0.227.0 (which was centuries ago), n8n has renamed the WEBHOOK_TUNNEL_URL configuration option to WEBHOOK_URL . In n8n 1.0, WEBHOOK_TUNNEL_URL has been removed. Update your setup to reflect the new name. For more information about this configuration option, refer to the docs here and here.

That was the solution, I was not aware of this change, thank you so much.
