@klkwarrior Can’t see where this -S is coming from. Can you please capture the HTTP traffic when this is happening?

Get your client ready but don’t start yet. Make sure you know the IP address it receives on DHCP later on. install tcpdump on your FOG server (e.g. sudo apt-get install tcpdump) run tcpdump: sudo tcpdump -w item_issue.pcap host x.x.x.x (put in the client’s IP address instead of x.x.x.x and leave the command running) boot up the client till you see the error message on screen - then stop tcpdump (ctrl+c), upload the item_issue.pcap file to some server/cloud and post a link here.
