# Set up a redirect from HTTP to HTTPS

**Note** : only one redirect option can be enabled on a CDN resource.

You can redirect HTTP traffic to HTTPS via API (more info in the [API documentation](https://gcore.com/docs/api-reference/cdn/cdn-resources/change-cdn-resource-1)) or in the Gcore Customer Portal.

To enable the redirect option in the Gcore Customer Portal, go to the CDN resource settings:

1\. Get a free Let's Encrypt certificate or add your SSL certificate in the General -> SSL section and save changes. More info in the guide "[Add an SSL certificate to deliver content over HTTPS](/cdn/ssl-certificates/add-an-ssl-certificate-to-deliver-content-over-https)".

The error "*You cannot enable redirect HTTP to HTTPS when HTTPS is disabled. Please enable HTTPS and add SSL certificate first* " means that you didn't add a certificate or that the issuing of a Let's Encrypt certificate for your account wasn't completed. As usual it takes about 15 minutes.
