Custom TTS Issue

Hi! I'm trying to use a custom TTS provider with Vapi (via their web widget).

I'm running a FastAPI server exposed publicly via a tunnel (tested via curl, works).
Endpoint: POST /synthesize (prints incoming requests).
Server runs with: `uvicorn main:app --host 0.0.0.0 --port 8000 --reload`
Custom TTS Provider
Custom URL: https://<my-tunnel>.loca.lt/tts (confirmed it's correct)
Saved the agent after setting this
Using correct
```
assistantID
```
assistantID
```
assistantID
```
assistantID
(e5eec97d-3f5d-4bdc-bf57-d479ead77a1a) in the script
Microphone access is allowed
Widget is rendered and starts listening
My FastAPI server never receives any request from Vapi
There are no errors shown in browser console or FastAPI logs
Widget just ends call after a few seconds with "Meeting has ended

Here's the screenshot of console

Any ideas or things I might be missing? I can share my FastAPI code and curl response if needed. Thanks in advance!
