I have managed to find all the times when there was an issue with connectivity - but it looks to me like a system problem. There are periods of hiatus where nothing is logged and it is these times when connectivity to the server breaks.
I would like you to check the windows event log through eventvwr.exe
and look at both the System
and Application
event logs for the periods around the times i give below.
You are using uPnP automatic mapping and your logs show success everytime it is refereshed and we refresh the automatic mapping every hour. You can see from this log extract that it is all perfect

So automatic port mapping is working fine for you.
However we have gaps in time in the logs. This could be a symptom of disk errors or other system issues and I am hoping that may be the windows event logs would shed some light on it
Times to check
There is a 7 minute gap here

So periods to look at within the windows event log are
September 24th 20:30 to 21:30
September 25th 17:30 to 18:30
September 26th 17:30 to 19:10
Other areas to explore is if you have any specific activity / program that kicks in at specific times
