Unable to verify domain

Unable to verify domain

My domain is hosted with Coffeecup S Drive. S Drive has no email function so I am tryhing to set up an alias via ZOHO for the email address sales@tonneaucoversstore.com I am trying to verify that I own the domain tonneaucoversstore.com using the HTML method. I believe the verify file was uploaded to the right path because when I click on http://www.tonneaucoversstore.com/zohoverify/verifyforzoho.html I see
this number: 1441913241496 But when I click the ZOHO verify button, I still get the error stating that zoho could not find the html file in the specified path.
Thanks for your help. Larry
