Cannot complete allocation error when running CoTurn test scripts? (Relay sometimes drops connection)

[NF]

Hi,

I'm using coturn to enable VOIP calling between two android devices on my own server. Currently I can set the coturn relay up and sometimes it recognizes that one of my devices is attempting to connect and binds the packet, but has no where to send it (telling me the relay isn't working entirely). I decided to try out the coturn test scripts outlined under section X at this link: https://github.com/coturn/coturn/blob/master/INSTALL 

The scripts all give me a "Cannot complete Allocation" error, but that's all that prints. Tracing back the coturn code tells me that possibly a port is being blocked, but I'm not sure. Here is my coturn log output when I start the server (IP redacted).

Let me know if you think you know what the problem might be.

Hi,

I am also facing same problem. But in my case call is connecting but showing black screen for receiver's stream. What could be the solution?

Regards,

Sachin.
