Interesting -- recently I had a similar situation and got the same error though the NAT settings were applied by the book.

It turns out, I left the wss.pem file out of reach (I messed up the permissions) as I am using WSS too. The error was the same as yours which led me to believe it was a socket binding issue.

Guys,

Just to let you know, I've downgrade to 1.2.17 and everything is working now without any configuration changes.

Thanks,
Arsen.

Hi guys,

I am trying to run freeswitch on Amazon AWS, but I am facing the following error:

2014-01-31 11:43:11.024549 [ERR] sofia.c:2500 Error Creating SIP UA for profile: internal (sip:mod_sofia@172.31.28.215:5060)
The likely causes for this are:
1) Another application is already listening on the specified address.
2) The IP the profile is attempting to bind to is not local to this system.

I am sure that the port 5060 is not used by any other application as well as 172.31.28.215 is an internal IP address of the instance. 

I have tried to configure mod_sofia as it described in this link:

Also I googled this error and tried to fix it with 
<X-PRE-PROCESS cmd="set" data="local_ip_v4=172.31.28.215"/>

All required ports are opened. 
Freeswitch git installation v.1.2.18 

Strange that I have never faced the same issue with my previous FS installations on EC2.

Thanks for advice!
Arsen.
