Error: The underlying connection was closed: An unexpected error occurred on a send. about fido HOT 2 OPEN

I was getting the same error. Well, all I get was 'Error: The underlying connection was closed: An unexpected error occurred on a send.'. I tried via the UI and also via -GetUrl - same result either way.

I tried it on another machine behind a different internet connection however and it worked.

It looks like the original site crapped out while trying to pull a list of languages as that's the next step I got when I ran it behind another internet connection. I changed the VM (vmware workstation, where I try any code/etc I haven't read through and tested thoroughly) I was testing in to point its DNS to google (8.8.8.8) and flushed DNS and tried again - same result.

I then tried it on another machine under the original site's internet and it worked on that machine. Then just for the sake of thoroughness I went back to the original test VM and tried again there - still failed.

My test VM is Win10 build 1709. The same-network machine where it worked was Win10 1809 (Enterprise LTSC). I'm not saying for sure that that is necessarily the root cause, but it's the only meaningful difference I can discern.
