Zoho CRM at Go Daddy Secure Certification Authority

Zoho CRM at Go Daddy Secure Certification Authority

i just noticed that one of my web-to-lead-forms isn't transmitting the leads back to my zoho crm account.  but i used the exact web-to-lead form at my other website and it worked fine.
the only difference is that the one not working was a Go Daddy Secure Certification Authority website.
is it because of that so the leads aren't being transmitted back??
sorry new to the field, would appreciate if someone can help.

thanks
