On the signup page (https://clickngo.cloudways.com/signup/) I get a mixed content warning:

Mixed Content: The page at 'https://clickngo.cloudways.com/signup/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://www.cloudways.com/en/'. This request has been blocked; the content must be served over HTTPS.

if I allow the the connection in chrome (allow unsafe scripts)
Chrome will sill not send the ajax request:

XMLHttpRequest cannot load http://www.cloudways.com/en/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://clickngo.cloudways.com' is therefore not allowed access.

Please fix this by enabling TLS on all sub domains.
