[Solved] YouTube RTMP Streaming Error

Jan. 03, 2026

We have identified cases where live streaming to YouTube via RTMP may fail to start or become unstable when using PRISM Live Studio.

When this issue occurs, users may see a “Failed to connect to the server” message in the PRISM Mobile app or PC app, preventing the live stream from starting.

Error screen

This issue is not caused by an error in the PRISM service. It has been confirmed to be related to recent IPv6 transition policies and ISP network infrastructure changes in certain countries, which may conflict with the default OBS-based streaming connection method.

Reference

Due to recent network infrastructure changes, users in India and Indonesia are advised to apply the settings below.

Additional Information

In regions where IPv6 network connections are unstable, using IPv4 may help improve connection stability to the streaming ingest server.

Once the network environment is stabilized, live streaming is expected to function normally without additional configuration.

We apologize for any inconvenience this may cause and will do our best to ensure stable service.

Thank you for your understanding.
