Look at the format of the URLs of the other links and correct the one for the accelerators. It's a hack that worked for me.
There was a slight misspelling in the download link. We have updated the request to team few days back it should get applied soon.
For those who might also face same issue, Sample wrong url (where / was missing):
Correct url (after adding / ) :
