# Enabling HTTPS with LetsEncrypt
Automatic LetsEncrypt setup and renewal are only available in the Docker installation. For other installation types, you can directly use Certbot.
LetsEncrypt is a free and simple way to allow safe and secure connections to your AzuraCast installation. With a valid SSL certificate, you can:
- Secure your connection to AzuraCast when administering your stations,
- Enforce security for all AzuraCast administrators via HTTP Strict Transport Security (HSTS), and
- Provide a secure listening endpoint to listeners, avoiding "Mixed Content" warnings when your radio signal is played from a secure web page.
# Important Considerations
Before setting up LetsEncrypt, you should make sure the following conditions are met:
- AzuraCast must be on its own domain or subdomain. You can't set up LetsEncrypt using only an IP address; you must have a domain (i.e.
mysite.com) or a subdomain (
radio.mysite.com) set up to point to your AzuraCast installation.
- AzuraCast's web server must be served on the default ports, 80 for HTTP and 443 for HTTPS. By default, AzuraCast is already set up this way, but if you've modified the ports to serve the site on a secondary port, you must switch the ports back to the defaults when setting up LetsEncrypt and when performing renewals.
# Enabling LetsEncrypt
Connect to your host server via a terminal (SSH) connection and execute the following commands:
cd /var/azuracast ./docker.sh update-self ./docker.sh letsencrypt-create
Answer the prompts as shown to complete the setup process.
# Renew a LetsEncrypt Certificate
The web service will automatically renew your LetsEncrypt certificates. If you provide an e-mail in the initial setup process, that e-mail will be used to send you reminders of upcoming expiration in the event that automatic renewal fails.
