DKIM Record Not Working

Hello Sir,

Domain: www.techtry.com

I created the dns entries of my domain following instructions from the link
https://www.zoho.com/campaigns/help/setup-spf-dkim.html

I created: zoho._domainkey.techtry.com

But It is still giving error, when checked it on http://dkimcore.org/c/keycheck
