Did you review sk113479 does it not apply to your case?

I looked at this ck but did not find any suitable solution to the problem there

According to sk113479, what is happening is the connection is terminated (either by the client or server) prior to the firewall being able to do a deep layer (application/URL Filtering/data/etc.) inspection. Basically the firewall has allowed the original connection based on OSI layers 1-4 because it is still has not passed data in layers 4-7 to determine the actual application/URL/Data/etc. in use by the connection. Since the packet was dropped prior to having this information, the firewall has not come up with a final match within the rule base. Without this final match, the connection would not create a log, so to make sure the connection is logged, the firewall uses this log to let you know the connection was attempted, but there was not enough information to reach a final match and determine if the connection should have been allowed or dropped. 

Watch the video in the sk - it goes into more depth about this. Wait for the final example - that is where this is explained in better detail.
