A nearly identical thing happened to me today, of all a sudden. None of my computers can use this download feature that was working fine this morning, and I haven't installed or uninstalled anything. In fact, when I encountered the problem, I tried uninstalling the Calibre, and even my anti-virus, but it didn't work; then I realised that none of my other computers work either.
I've tried playing with the Preferences/Metadata_Download, trying to change the server and ticking and unticking options, but nothing works.
I hope anyone has a suggestion, but it seems to be server related somehow. My Internet works fine, by the way.

In fact, earlier I noticed the error "No module named polyglot.builtins", but now it says something else (see box above). This is what I get when I try again:
