### Setting-up HTTP redirection
The Gitea server is only able to listen to one port; to redirect HTTP requests to the HTTPS port, you will need to enable the HTTP redirection service:
```ini
[server]
REDIRECT_OTHER_PORT = true
; Port the redirection service should listen on
PORT_TO_REDIRECT = 3080
```
If you are using Docker, make sure that this port is configured in your `docker-compose.yml` file.
## Using Let's Encrypt
[Let's Encrypt](https://letsencrypt.org/) is a Certificate Authority that allows you to automatically request and renew SSL/TLS certificates. In addition to starting Gitea on your configured port, to request HTTPS certificates Gitea will also need to listed on port 80, and will set up an autoredirect to HTTPS for you. Let's Encrypt will need to be able to access Gitea via the Internet to verify your ownership of the domain.
