It seems like you have several problems here.<br>

</span>In your terminal:<br>
<br>
export G_MESSAGES_DEBUG=all<br>
export NICE_DEBUG=all<br>
<br>
then run your program. This will print the full libnice debug logs to<br>
the terminal.<br>

</span>I would suggest trying with master. There have been a couple of fixes<br>
since 0.1.13 to do with state handling and signalling.<br>

<br>
</span>Almost everything to do with libnice behavioural differences is to do<br>
with network environment! Note that ICE negotiation is not guaranteed<br>
to succeed in some network environments (for example, between two peers<br>
which are each behind a symmetric NAT).<br>
<br>
Do you have a TURN relay set up?<br>

<br>
</span>If you are setting the NiceAgent pointer to NULL without calling<br>
g_object_unref() first, you are leaking the memory from the NiceAgent,<br>
plus all the resources (including network ports) which it’s using. This<br>
might be contributing to the ICE failures you are seeing, if there are<br>
no more forwardable ports left for the new NiceAgent to use.<br>
<br>
If you are getting an assertion when calling nice_agent_new() after<br>
unreffing the old instance, that indicates a bug somewhere – probably<br>
somewhere else in your code – which needs investigating.<br>
