@rmishra1004 is this happening on all hosts or just this one? Have you tried hitting the ‘reset host encryption keys’ on the host in the webgui?
If you copy past the url that fails, what happens? I believe you should see an error message like this

{"error":"im"}

when going to it in a browser

Sorry for my late reply, re: the other thread that I started on this. I don’t manage the hardware-side of the FOG server so i couldn’t get the file specified. I was also furloughed from work for some time, so I’ve missed the earlier updates.
