When trying to set up a webhook with the following data:
Webhook URL: http://IP_ADDRESS:9090/api_gateway/MV06510991-94519/set_custom_property
Seeing below error went trying to transmitting:
2751115: Error while transmitting webhook to url(s) ERROR to webhook channel (channel,org)=(null,TENANTID): java.net.ConnectException: Timeout connecting to [/IP_ADDRESS:9090]
Release : 21.3
The DX Oi will only send the Webhook notification through port 80 or 443. Please change the URL to the working port.
You can create a port forwarding internally from (80/443) to 9090 If needed.
