Comcast Norton Firewall

My third party online backup program (SOS Online Backup) is no longer connecting to its home server.  

 

SOS help desk says to ensure that the firewall allows access out.  

 

I've checked the firewall rules in my Comcast Norton Suite (Ver. 21.2.0.38) and it *appears* that all the backup program's exe files are set to "allow." 

 

The reason I'm posting here is that the last successful backup was May 21, which I believe was about the time of that massive 200mb+ download/update. 

 

Could that Comcast Norton update have changed something? 

 

Is it possible there are other "firewall rules" I should be checking?  Any others have program access glitches after the big update? 

 

If you have any thoughts, they would be most appreciated.
