Issues with Self-Hosted n8n on Google Cloud (Docker Install)

🔹 Google OAuth Issues

• Cannot log into Google services (OAuth callback fails).

• Firewall rules updated, still failing.

🔹 Telegram Webhook Issues

• Error:

Bad Request: Webhook can be set up only on ports 80, 88, 443, or 8443.

• n8n runs on 5678, proxied via Nginx to 443, but Telegram still rejects the webhook.

• SSL and firewall rules are properly configured.

🔹 Other API Connection Failures

• Some APIs fail due to firewall restrictions.

• Ingress/Egress rules allow all traffic, but still blocked in some cases.

Need Help With:

1. Getting Google OAuth to authenticate on self-hosted n8n.

2. Fixing Telegram webhook issue (proxying not working).

3. Ensuring all APIs can connect without firewall blocks.

Any insights appreciated. Thanks! 🚀
