Revolution Slider Fails to Upload

I downloaded Revolution Slider but it’s not uploading on my Wordpress. I am uploading the .zip file. After a few minutes the page changes and says:

“This site can’t be reached
The webpage at http://mysite.com/wp-admin/update.php?action=upload-plugin might be temporarily down or it may have moved permanently to a new web address.
ERR_CONNECTION_ABORTED”

Try uploading the unzipped version via FTP. If you need further help message me here
