I think it was your server issue or something else which was trying to stop you from being visiting that page. I tried to access by hard reloading page & it worked check the screenshot: http://prntscr.com/opmril
Try to hard reload the page by hitting CTRL+F5 multiple time if its not works then you can do it the following way. First right click on the page & click inspect element then right click on reload button of the browser you’ll see “Empty cache & Hard reload” click on this one check the screenshot: http://prntscr.com/opmtty
Hopefully this will solve the issue.
