Webhook 403 Error – WAHA blocking requests to 172.17.0.1

[ZoltanAB]

Hi 👋,

I'm running WAHA in Docker and attempting to send webhook events to a local Nginx server from within the container.
🔧 Setup:

WAHA started without --network=host

Webhook URL is set to:

http://172.17.0.1:5000/webhook-proxy.php?port=3001

Nginx is listening on the host at 172.17.0.1:5000 and responds correctly to manual curl requests from inside the container.

✅ What works:

curl http://172.17.0.1:5000/webhook-proxy.php?port=3001 from inside the WAHA container works perfectly and reaches Nginx.

Nginx logs show manual requests being handled as expected.

❌ What fails:

When WAHA tries to POST to the same URL, I receive:

"You are forbidden to connect to client_connect_invalid_ip"

This implies WAHA internally blocks webhooks going to 172.17.0.1 (and possibly other local subnet IPs).
💬 Question:

Is there a recommended way to allow WAHA to POST webhooks to the host's IP (e.g. 172.17.0.1)?

Or, is using --network=host and http://localhost:5000/... the only supported solution for local webhook delivery?

Any guidance would be appreciated 🙏

Thanks for your great work on this project!

Later edit, WAHA docker is using a HTTP and a HTTPS_PROXY.

Either use service name or connect properly using docker networks

"You are forbidden to connect to client_connect_invalid_ip"

It's your app/nginx/etc
