any ideas why i would get this error message when I try to download the speed test servers? It was working then stopped... not sure if it's something I did. I'm pretty new to fortinet. 

Fortigate-60F # exe speed-test-server download

I am getting the same error on a 60F when trying to download the speed test servers, which makes it impossible to use the speed test via GUI or CLI. I have opened a ticket but have not yet had time to have a Fortinet technician see the issue for themselves.
