To add SSL to your site please make sure to make the following changes in the control panel of your domain in your registrar account (where you originally purchased the domain):
A record - Host --> @ (empty) points to --> 34.96.116.138
CNAME - Host --> WWW points to --> im-router-service.com
To create an automatic redirection from http to https, please add the next code to your site’s Head-tag. (You can do so through Settings> Head Code):
<script language="JavaScript">
if(window.location.protocol != 'https:')
{ location.href = location.href.replace("http://", "https://"); }
</script>
