This article will explain how to add an SSL Certificate from the free Let's Encrypt Certificate Provider with GridPane using webroot domain verification. This will allow your site to be served by the encrypted HTTPS protocol, and your visitors will also benefit from the speed increased enabled by HTTP2 which only works via HTTPS.
Webroot domain verification is the simplest method, but it requires that your GridPane site domain has DNS records pointed to the GridPane managed server IP.
GridPane does not enable/disable SSL for the site, but rather it manages SSL on a per domain basis for each domain attached to a site. This means SSL management is done through the domains tab.
In this Knowldege Base article we will use a site's primary domain to demonstrate, however the same functionality and process is true for any added Alias and Redirect domains.
Note: Within this article we're going to use
an-example.site to illustrate things. When following along with this knowledge base article please make sure you substitute this string for your real domain name.
Step 0. Ensure DNS records resolve to the server
We recommend having records for both the root domain and for the www host domain, for example:
root domain, you will need an
A record set to the IP of the server.
www host domain you can either use an
A record or a
For the webroot method GridPane currently checks for domain resolution directly to the server, this is both to avoid hitting any LE limits and to verify which domains resolve for grabbing the correct cert. GridPane will grab certs for whatever domains are possible, so if you forget your www record then the system will provision an SSL certificate without it.
You can check your domains dns resolution using any one of many online websites, or one of several command line tools.
Step 1. Go to the Sites Section of the GridPane Control Panel
Click on the sites link in the GridPane main menu to go to the Sites management page.
Step 2. Open the Site Customization Panel for your Active site
In the Active Sites panel, click on the domain in the URL column to open the Site Customization pop up box for the site you wish to update.
Step 3. Enable Lets Encrypt SSL for your domain
Open the Domains tab in the site customizer
Locate the SSL toggle for the domain that you wish to provision an SSL for

GridPane will begin provisioning SSL for your site's domain. You will see Notifications pop up in the top right corner of your browser as the SSL attempts progress.
Enabling an SSL can take some time.
You can keep track of the notifications as they inform you about the progress of the SSL attempt. Alternatively, you can check the SSL provision log, available from the logs tab of the site customizer. The SSL provision attempt outputs every step of the process to the log.
