Problem Symptoms
In the webhook logs or via email you receive the following message: Failed to connect to the webhook endpoint
Description
We wait 10 seconds for the host to respond, there are a few reasons why the webhook endpoint might be having issues.
- IP blocked
- Network delays or packet loss in the route
- Host CPU congestions
Resolution
You can test for packet loss / latency via traceroute or MTR to the IP of the host you entered as your webhook endpoint.
