application not working.

I had a customer connecting to an application from trust to untrust. It was working and then suddenly stopped working.

I could see in the logs it was coming as port 443 and application -incomplete and then next day it started working with port 443 and application ssl. Any logical reason why this would happen. Running 7.0.6 PA200.

Application incomplete usually means that the 3-way TCP handshake didn't complete.  It's possible that the service on untrust was not working properly at the time, or that their connection to the Internet was disrupted.  

 

You can add additional columns to your traffic log to show # of packets sent/received.  If you see a lot of packets sent, but nothing received for those traffic flows, then that would point to one of the scenarios above.
