- `STARTUP_TIMEOUT`: **0**: Shutsdown the server if startup takes longer than the provided time. On Windows setting this sends a waithint to the SVC host to tell the SVC host startup may take some time. Please note startup is determined by the opening of the listeners - HTTP/HTTPS/SSH. Indexers may take longer to startup and can have their own timeouts.
If you are using Docker, make sure that this port is configured in your `docker-compose.yml` file.
## Using Let's Encrypt
## Using ACME (Default: 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.
[ACME](https://tools.ietf.org/html/rfc8555) is a Certificate Authority standard protocol that allows you to automatically request and renew SSL/TLS certificates. [Let's Encrypt](https://letsencrypt.org/) is a free publicly trusted Certificate Authority server using this standard. Only `HTTP-01` and `TLS-ALPN-01` challenges are implemented. In order for ACME challenges to pass and verify your domain ownership, external traffic to the gitea domain on port `80` (`HTTP-01`) or port `443` (`TLS-ALPN-01`) has to be served by the gitea instance. Setting up [HTTP redirection](#setting-up-http-redirection) and port-forwards might be needed for external traffic to route correctly. Normal traffic to port `80` will otherwise be automatically redirected to HTTPS. **You must consent** to the ACME provider's terms of service (default Let's Encrypt's [terms of service](https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf)).
By using Let's Encrypt **you must consent** to their [terms of service](https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf).
Minimum setup using the default Let's Encrypt:
```ini
[server]
PROTOCOL=https
DOMAIN=git.example.com
ENABLE_ACME=true
ACME_ACCEPTTOS=true
ACME_DIRECTORY=https
;; Email can be omitted here and provided manually at first run, after which it is cached
ACME_EMAIL=email@example.com
```
Minimumg setup using a [smallstep CA](https://github.com/smallstep/certificates), refer to [their tutorial](https://smallstep.com/docs/tutorials/acme-challenge) for more information.
