[libnice] server reflexive address not in the candidates list

[Philip Withnall]

That is potentially a bug, but it’s hard to tell from the information
you have provided.

Could you please file a bug against libnice on
phabricator.freedesktop.org, with information from setting
G_MESSAGES_DEBUG=all NICE_DEBUG=all environment variables when running
the test?

Thanks,
Philip
