Allocate Error Response error-code: 401

[Yves]

I am using TurnServer version 0.4
The SIP client is x-lite 4.0

Here is the message captured by the wireshark.

STUN Message: Binding Request
(the last message repeated many time)
…
STUN2 Allocate Error Response error-code: 401 (Unauthorized) Unauthorized realm: demo.com with nonce

I can make some call through the TURN server even my client is "Unauthorized".
But tt is difficult to make calls through the TURN server for some time.

Does anyone can tell what is the problem? Thanks
