Let's Encrypt availability

Let’s Encrypt certificates on Scalingo

If you want a Let’s Encrypt certificate on Scalingo, it is as simple as adding your own domain name. We automatically generate a certificate for every domain added to the platform. Let’s Encrypt certificates have a 90 days validity. We follow Let’s Encrypt recommendation and renew them every 60 days automatically. You do not need to do anything manually!

If you prefer to use a certificate signed by a different certificate authority, feel free to add it by following the instructions.

If you forget to renew your custom certificate and it expires, or if you delete it, a Let’s Encrypt certificate will automatically and immediately replace it. Hence your application will always be available using HTTPS.

Note that Let's Encrypt wildcard certificates are not globally available. If you add such a custom domain, we will not be able to create the Let's Encrypt certificate.

Let’s Encrypt certificate statuses

On the dashboard, you may find your Let’s Encrypt certificate with various statuses:

  • Pending DNS: when you link a domain name to your application, we wait for it to target our infrastructure before generating the certificate. We check the DNS record automatically every 60 seconds.
  • Creating: our infrastructure is exchanging messages with Let’s Encrypt servers to generate your certificate.
  • In use: your website is available using HTTPS connections thanks to a Let’s Encrypt certificate.
  • Not used: your website is available using HTTPS connections thanks to a custom certificate. If it expires or if you remove it, your website will be available using HTTPS connections thanks to a Let’s Encrypt certificate.
