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 do not deliver wildcard certificates. If you add such a custom domain, we will not be able to create 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.
