I recently upgraded to the 4.1 OS from 4.0.1. The firewall settings are fine but for some reason whenever the firewall tries to download any new software like 4.1.1, GlobalProtect, Dynamic Updates it keeps getting the error "Failed due to network failure".
I have checked and made sure that the Managment Interface is not being blocked by URL or Security policies. I even see successful connections to update server but the error still keeps coming up.
I had the same issue on 4.1.0.
The Check now in Software only generated the following error message:
"Failed to check Content content upgrade info due to generic communication error"
I resolved the issue by doing this:
Software list is now updated and 4.1.2 are now downloading 🙂
