android nativecall turn server problem

useing android nativecall demo is default config stun local network test works fine

but Set add helperserver TURN_UDP, TURN_TCP and test another network balck screen

turn server log : incoming packet message processed, error 401: Unknown error

Do we have any suggestions?

Start with the Android nativecall demo and compare its default STUN configuration with the added TURN_UDP and TURN_TCP helperserver settings. Reproduce the black screen from another network and review the TURN server log showing “401: Unknown error”; done requires identifying the configuration or signaling failure and confirming a working remote-network call.
