I am also facing the same issue, same error. STUN server failed, changed to TURN server, it work, 1-2 days later, it will fail. Have posted my issues here,
Inconsistent issue with streamlit-webrtc and streamlit.

Perhaps you should too…
Original component - is also not working https://webrtc.streamlit.app/

strange that ppl are ignoring this issue…This is so unstable.
