Acquiring SSL certificate
You can add a free Let's Encrypt certificate from the Domain - SSL view. All you have to do is tick the domain or domains, for which you'd like to add certificate to.
You can get an option to add your own certificate by other service provider by subscribing to our Premium plan.
For using only encrypted traffic on your website, you can choose to Force SSL. Go to your domains menu and click on the cogwheel icon behind the domain name, find 'Force SSL' and choose 'Always use SSL' option.
NB! Make sure the SSL certificate is activated before you force SSL.
You can check that by typing your website's address on URL bar with https:// prefix and when it displays your site, you're good to go. Otherwise you lose access to your website.
