CNAME subdomain issues

CNAME subdomain issues

I added a CNAME to my domain for the desired subdomain (helpdesk.riverfoursquare.net) and pointed it to 'customer-support.zoho.com.'

' https://desk.zoho.com/support/riverfoursquare' redirects to ' https://helpdesk.riverfourquare.net/support/riverfoursquare', but the page cannot be displayed.

Right now, I'd prefer to just switch it back to the default. Is there a way I can do that myself without needing to involve you guys?

Thanks!
