Connection error when trying to submit payment

I'm using Gravity Forms for my user registration form. The registration process works fine but after I choose my membership and click the submit button, the page hangs and then I get an err_connection_timed_out error (see attached). Same issue in Firefox.

I have Authorize.Net set up. I've tried this is in both sandbox and live mode with the same result.

I have no idea what to do to trouble shoot and fix this. Can someone help?

    Hello John,

    This is happening because requires SSL even for the sandbox mode. If you look closer than you will see that checkout page was redirected to https url. And if you don't have SSL certificate on your website then it will results with connection timeout error.
    So in order to use you have to purchase SSL certificate and install on your server and then it will work.

    kind regards,

Thank NAME, for their help.
