[BUG] Ant SDK Flutter Connection Issue on True Move/True Broadband Networks (Thailand)

[BUG] Ant SDK Flutter Connection Issue on True Move/True Broadband Networks (Thailand)

Issue Summary

Applications using Ant SDK Flutter fail to properly connect to Ant SDK servers when operating on True Move/True Broadband networks in Thailand. Users experience black screens and cannot view video streams.

Issue Details

Our testing reveals:

1. The app successfully establishes WebSocket connections to Ant SDK servers
2. WebRTC successfully exchanges SDP and ICE candidates
3. However, no video frames are received, resulting in a black screen
4. After attempting to connect for a period, the connection is terminated
5. This issue occurs exclusively on True Move/True Broadband networks; other networks work properly

Key Log Information

1. WebSocket connection successful:

I/flutter (20715): onOpen
I/flutter (20715): [13:58:30] ℹ️ INFO [stream] [ANT_SDK_LOG] State changed to: HelperState.ConnectionOpen
I/flutter (20715): [13:58:30] ℹ️ INFO [stream] [ANT_SDK_LOG] WebSocket connection state: Connected

2. WebRTC successfully creates SDP and exchanges candidates:

I/flutter (20715): send: {"command":"takeConfiguration","streamId":"XXXXXXKB8De7DJzO75064XXXXXXX","type":"answer","sdp":"v=0\r\no=...

3. No video frames received:

I/org.webrtc.Logging(20715): EglRenderer: Duration: 4049 ms. Frames received: 0. Dropped: 0. Rendered: 0. Render fps: .0. Average render time: NA. Average swapBuffer time: NA.

4. Connection terminated:

I/flutter (20715): bye: XXXXXXKB8De7DJzO75064XXXXXXX
I/flutter (20715): [13:58:25] �� DEBUG [stream] _handleDisconnect error : การเชื่อมต่อถูกยกเลิก
I/flutter (20715): [13:58:25] ℹ️ INFO [stream] [ANT_SDK_LOG] Attempting to reconnect (1/5)

Our Suspicions

We suspect the following issues may be occurring:

1. WebRTC port blocking on True networks
2. UDP traffic limitations affecting WebRTC streams
3. Incomplete NAT traversal

Proposed Solutions to Try

1. Add TURN Servers to the WebRTC configuration
2. Adjust ICE Config to use iceTransportPolicy: 'relay'
3. Increase connection timeouts to accommodate less stable networks

Thank you for your assistance.

Greetings @kimPongsakorn,

Thanks a lot for the detailed explanation and logs — really appreciate the effort you've put into breaking this down.

From what you’ve described, it does sound like a network restriction on True Move/True Broadband, possibly blocking UDP or interfering with NAT traversal. To work around this, we recommend trying the connection with a TURN server configured.

A TURN server forces media to relay over TCP/TLS if direct peer-to-peer connections fail, which should help in restrictive networks like this.

If you're able to test with a TURN server and update the ICE config to use iceTransportPolicy: 'relay', that would help confirm if this is indeed a network-level issue.

Let us know how it goes — happy to help further based on the results!

[kimPongsakorn]

Currently, I'm using the iceServers configuration as { urls: 'stun:stun.l.google.com:19302' } but I'm still experiencing connection issues. Do I need to modify this configuration, or do you have any recommended settings I should try?

[filip-ams]

The current config you're using (stun:stun.l.google.com:19302) is a STUN server, which helps with NAT traversal but doesn’t relay media. In restrictive networks like the one you’re testing on, media may not be able to flow directly between peers, which is where a TURN server becomes necessary. You can read up a bit regarding stun/turn servers in our documentation here:
