Will HTTP/2 work once a domain gets Let’s Encrypt?
When you install Let’s Encrypt all people who visit your website through an encrypted connection (https) and use a modern browser that supports HTTP/2 (such as all the latest versions of Chrome, Firefox, Safari) will receive your content served through the newer and faster HTTP/2 protocol.
Please note that depending on the application you use you may need to perform some additional configurations on your website to make it work properly with the SSL after the Let’s Encrypt installation.
For example if you have installed Let’s Encrypt on a WordPress or a Joomla website, you may want to use our Toolkit to enable https.
If you wish your website to be accessible ONLY through https, you may want to redirect all your http traffic to go to https by adding few lines to your .htaccess file.
