noob question: getting a "site can't be reached" error on export

I have selected a region to download (shanghai) but when I hit “export” I keep getting an error saying that the site cannot be reached:

Here is the url it is trying to reach:

and here is the error message:

This site can’t be reached
The webpage at might be temporarily down or it may have moved permanently to a new web address.

Am I doing something terribly wrong?


Your area is too large, try one of the other download options mentioned on the “export” page.
