# Configuring HTTPS

To configure HTTPS on the controller, follow these steps:

1. Access the web interface of the controller. A warning message will appear from the browser due to the self-signed certificate. Select Advanced and accept the risk to continue.

2. Navigate to Settings and select the HTTPS tab.

3. In HTTPS settings, select Create CA CSR.

4. In the pop-up window, select Create to create a certificate signing request and then select Close when the download is complete.

5. Sign the certificate signing request and upload the resulting CA certificate to the controller.

6. Select Generate server certificate, enter the Subject Alternative Names (SAN) in the specified format, and click Generate.

7. After the generation is complete, a pop-up window is displayed and the session will restart automatically.
