Thanks to the suggestion, the tcpdump software helped me to understand that the host did not send any data packet to the FOG server during the closing phase of the snap-in. All this was due to the fact that my script assigns a static IP to the Host when certain parameters occur, so, in the IP assignment phase, the Host was offline and the snap-in was unable to communicate with the FOG server. So I solved the problem by inserting a 10-second pause in the script with the powershell start-sleep command, allowing the Host to return online before closing the snap-in.
I wanted to thank you for your availability and tell you that you are doing a great job with FOG.

Thanks for your help, I will do what you have requested and I will send you the file

Hi I have a problem with the FOG Snapin works.
The version of FOG installed is 1.5.2.
I created a snap-in with a powershell script that runs correctly on the host, but in task management,
its activity is permanently running, relaunching the same snap-in on the host, always running it correctly
until I manually delete the task from the task management. So I went to see the log file,
the result of the snap-in is shown below:

I noticed that it is a communication error but if I take the url:

http://10.16.16.3/fog/service/snapins.checkin.php?taskid=117&exitcode=0&mac=9C:5C:8E:20:82:E6&newService&json

and I report it in any browser he permanently closes me the activity of the snapin in question.
At this point I ask you if anyone can help me, because I do not know if it’s a configuration problem or a software bug.
In addition I tried to uninstall and reinstall the FOG Client, to reset the encryption data without solving the problem.
