Hi, I’m trying to configure a webhook connection with VAPI but it is not sending, while clicking the test button it shows an error message Network error: Unable to connect to the server. This could be due to CORS restrictions, the server being down, or network connectivity issues. https://cdn.discordapp.com/attachments/1358777834436300984/1358777835153784965/IMG_7882.jpg?ex=67f513f8&is=67f3c278&hm=8d150bb90448b755a2a1f43054544eba43f3148a7f8e22db12a02829df7860fe&

Hi there! 👋 I see you're having trouble with a network error while trying to configure a webhook connection with VAPI. I can't see the specific details of your setup from the error message alone, but I can definitely help you troubleshoot this network error based on the information you've provided. Let me walk you through some troubleshooting steps to resolve this issue: ## Check Your Server URL Configuration First, verify that the webhook URL is correctly configured in VAPI: - Ensure the server URL you've entered in the VAPI Dashboard is correct and accessible from outside your network - Confirm the URL format is correct (should start with

https://

and not include "https" twice) ## Troubleshoot CORS Restrictions The error mentions CORS restrictions as a possible cause: - If you're using a custom server, you may need to configure CORS headers at the server level - According to [VAPI documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1342210515883261952), custom headers need to be configured at the server level, not directly in the tool configuration ## Check If Your Server Is Down To verify if your server is running properly: - Check your server logs for errors or intermittent downtime - Try to manually access your webhook endpoint using tools like Postman or cURL - Ensure your local server is running on the expected port ## Network Connectivity Troubleshooting For general network connectivity issues: - Verify that your network allows outgoing connections to

api.vapi.ai

- Check if there are any firewalls blocking the connection - Ensure you have a stable internet connection - Try connecting from a different network to rule out local network issues ## Additional Steps - Simplify your webhook configuration to test basic connectivity - Check that your endpoint is a

POST

endpoint, as [VAPI requires](https://docs.vapi.ai/server-url/developing-locally)

Hey, could you share your server URL or tool call ID so I could take a look in the logs if I find anything?
