I'm glad to hear that your initial test worked, but I'm sorry to hear you're experiencing issues now. The "Twilio Connection Failed" error can occur for a few reasons. Here are some common causes:
1. **Network Issues**: There might be network connectivity problems between your server and Twilio's servers.
2. **Twilio Service Disruption**: Twilio's services could be experiencing an outage or maintenance.
3. **Authentication Problems**: The Twilio Account SID or Auth Token may have been changed or may no longer be valid.
4. **Webhook Configuration**: The webhook URL might be incorrect, or the server at the webhook URL might not be responding correctly.
5. **Account Restrictions**: There could be restrictions on your Twilio account that are preventing the call from being placed.
6. **API Issues**: There might be an issue with the API call being made to Twilio, such as incorrect parameters or headers.
To troubleshoot this issue, you can:
- Check Twilio's status page to see if there are any reported outages or incidents.
- Verify that your Twilio Account SID and Auth Token are still correct and have not been regenerated.
- Ensure that your webhook URL is correct and that the server is up and running.
- Review any recent changes to your account or webhook server that might affect the call setup.
- Check your network connectivity to ensure there are no issues on your end.
If you've gone through these steps and are still facing the issue, it might be best to reach out to Twilio's support for a more detailed investigation into the problem. If you need further assistance or have more details to provide, please let me know!
