How do I add Simple SSL to my site?

Updated on January 4th, 2022


This article will walk you through installing a free certificate with Simple SSL. If you’d like to install a third-party SSL certificate instead, check out this guide:

Table of Contents:

1. Navigate to the site’s dashboard
2. Find the appropriate domain and Enable SSL
3. Select the domains you’d like to secure
4. Review domains that failed the DNS checker and complete the setup
5. Verify SSL status
6. Error Messages

Navigate to the site’s dashboard

  1. From the main menu, click Sites.
  2. From your site list, click on the site you’d like to enable Simple SSL on.

Find the appropriate domain and Enable SSL

  1. On the Domains card, click the Enable SSL button next to one of the domains you want a certificate for.

Select the domains you’d like to secure

  1. Select “Yes, use Simple SSL”.
  2. Select any or all of the domains by checking the appropriate box. Keep in mind that DNS for every domain selected will need to be pointed properly to the Flywheel site’s IP address, or Simple SSL installation will fail for those domains.
  3. You can view the DNS status of each domain on the domain selection screen. For example, in the image below, you can see that the first two domains have been verified by our DNS checker as having been correctly pointed to the Flywheel IP, indicated by the green checkmark.


Simple SSL supports up to 50 domain names per certificate. If your site has more than 50 domains please reach out to our friendly Happiness Engineers!

Simple SSL does not yet provide the ability to secure wildcard domains. If you’d like to secure subdomains, you’ll want to do so by adding each subdomain individually to the Simple SSL certificate.

Review domains that failed the DNS check and complete the setup

  1. Any domains that are not pointed to Flywheel will show an orange warning icon. Double-check the DNS settings for this domain (a DNS checker tool can be helpful), and then click the Check DNS Again button to retry.
  2. Once you’re satisfied with the results of the DNS check, click that green Complete SSL Setup button, and our system will get to work installing SSL for you!
  3. It can take up to 30 minutes to fully install the SSL certificate. You’ll receive an email from Flywheel when your domains are secured.


If you are pointing DNS via a proxy, like Cloudflare or Sucuri, the Flywheel DNS checker will not be able to confirm that DNS is pointed to Flywheel. If you are sure that DNS is set up correctly, feel free to ignore this warning.

If you’re pointing your domain through Sucuri, please make sure that the Forward Certificate Validation to Hosting setting is enabled to ensure validation.

Verify SSL status

  1. The SSL Status column will display the certificate type for each domain or the Enable SSL button for domains not yet covered by a certificate.
  2. A lock and shield emblem will display on your site’s thumbnail image, signifying that the primary domain on the Flywheel site is secured by SSL.


Error Messages

If Simple SSL fails to validate, you may encounter one of the following error messages:

These error messages indicate that Simple SSL failed to validate because the DNS for one or more domains is not properly pointed to the site’s Flywheel IP address. Check the domain’s DNS settings and try enabling Simple SSL again.
