Running Gogs behind a reverse proxy allows you to serve it on standard ports (80/443) with a clean and nice URL in the browser address bar, add TLS termination, and integrate with existing web server infrastructure.

<Note>
  Make sure the `EXTERNAL_URL` in your `custom/conf/app.ini` matches the actual URL users will access. When using a reverse proxy for TLS termination, keep `PROTOCOL = http` in Gogs and set `EXTERNAL_URL` to `https://`. The reverse proxy handles the encryption, and Gogs communicates with it over plain HTTP on the local network.

## Caddy

<Tabs>
  <Tab title="Standard">
    Add the following server block to your `Caddyfile` and reload:

    ```caddy
    gogs.example.com {
        proxy / http://localhost:3000
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = https://gogs.example.com/
    ```

    <Tip>
      Caddy automatically provisions TLS certificates via Let's Encrypt when you use a domain name.
    </Tip>
  </Tab>
  <Tab title="Subpath">
    To serve Gogs under a subpath, note the trailing `/`:

    ```caddy
    example.com {
        proxy /gogs/ http://localhost:3000
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = https://example.com/gogs/
    ```
  </Tab>
</Tabs>

## NGINX

<Tabs>
  <Tab title="Standard">
    Add the following `server` block inside the `http` section of your `nginx.conf` (or in a file under `sites-available`), then reload the NGINX configuration:

    ```nginx
    server {
        listen 80;
        server_name gogs.example.com;

        location / {
            proxy_pass http://localhost:3000;
        }
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = http://gogs.example.com/
    ```
  </Tab>
  <Tab title="Subpath">
    To serve Gogs under a subpath, note the trailing `/` on both the `location` and `proxy_pass` directives:

    ```nginx
    server {
        listen 80;
        server_name example.com;

        location /gogs/ {
            proxy_pass http://localhost:3000/;
        }
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = http://example.com/gogs/
    ```
  </Tab>
  <Tab title="HTTPS">
    Install [Certbot](https://certbot.eff.org/) and obtain a [Let's Encrypt](https://letsencrypt.org/) certificate:

    ```bash
    sudo apt install certbot python3-certbot-nginx
    sudo certbot --nginx -d gogs.example.com
    ```

    Certbot will automatically modify your Nginx configuration to use HTTPS. Your Nginx server block will look similar to:

    ```nginx
    server {
        listen 443 ssl;
        server_name gogs.example.com;

        ssl_certificate     /etc/letsencrypt/live/gogs.example.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/gogs.example.com/privkey.pem;

        location / {
            proxy_pass http://localhost:3000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
        }
    }

    server {
        listen 80;
        server_name gogs.example.com;
        return 301 https://$host$request_uri;
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = https://gogs.example.com/
    ```

    Certbot sets up automatic renewal via a cron job or systemd timer. Verify with:

    ```bash
    sudo certbot renew --dry-run
    ```
  </Tab>
</Tabs>

### Large file uploads

If you encounter HTTP `413 Request Entity Too Large` errors when pushing large files through NGINX, add `client_max_body_size` to your server block:

```nginx
server {
    listen 80;
    server_name gogs.example.com;

    client_max_body_size 50m;

    location / {
        proxy_pass http://localhost:3000;
    }
}
```

<Tip>
  Adjust the `client_max_body_size` value to match or exceed the maximum file size you expect users to push. The default NGINX limit is only 1 MB.
</Tip>

## Apache 2

<Tabs>
  <Tab title="Standard">
    Create or edit your virtual host configuration file (e.g. `/etc/apache2/vhost.d/gogs.conf`):

    ```apache
    <VirtualHost *:80>
        ServerName gogs.example.com

        ProxyPreserveHost On
        ProxyRequests off
        ProxyPass / http://127.0.0.1:3000
        ProxyPassReverse / http://127.0.0.1:3000
    </VirtualHost>
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = http://gogs.example.com/
    ```
  </Tab>
  <Tab title="Subpath">
    To serve Gogs under a subpath, omit the trailing slash after the port number in the `ProxyPass` directives:

    ```apache
    <VirtualHost *:80>
        ServerName example.com

        <Proxy *>
            Order allow,deny
            Allow from all
        </Proxy>

        ProxyPass /gogs http://127.0.0.1:3000
        ProxyPassReverse /gogs http://127.0.0.1:3000
    </VirtualHost>
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = http://example.com/gogs/
    ```
  </Tab>
  <Tab title="HTTPS">
    Enable the `ssl` module in addition to the proxy modules:

    ```bash
    sudo a2enmod proxy proxy_http ssl
    sudo systemctl restart apache2
    ```

    Apache virtual host configuration:

    ```apache
    <VirtualHost *:443>
        ServerName gogs.example.com

        SSLEngine on
        SSLCertificateFile    /path/to/cert.pem
        SSLCertificateKeyFile /path/to/key.pem

        ProxyPreserveHost On
        ProxyRequests off
        ProxyPass / http://127.0.0.1:3000/
        ProxyPassReverse / http://127.0.0.1:3000/
    </VirtualHost>

    # Redirect HTTP to HTTPS
    <VirtualHost *:80>
        ServerName gogs.example.com
        Redirect permanent / https://gogs.example.com/
    </VirtualHost>
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = https://gogs.example.com/
    ```
  </Tab>
</Tabs>

## lighttpd

<Tabs>
  <Tab title="Standard">
    Add the following to your lighttpd configuration:

    ```lighttpd
    server.modules += ( "mod_proxy" )

    $HTTP["host"] == "gogs.example.com" {
        proxy.server = ( "" => ( ( "host" => "127.0.0.1", "port" => "3000" ) ) )
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = http://gogs.example.com/
    ```
  </Tab>
  <Tab title="Subpath">
    To serve Gogs under a subpath, requires lighttpd **1.4.46 or later** for the `proxy.header` directive:

    ```lighttpd
    server.modules += ( "mod_proxy" )

    $HTTP["url"] =~ "^/gogs/" {
        proxy.server = ( "" => ( ( "host" => "localhost", "port" => "3000" ) ) )
        proxy.header = ( "map-urlpath" => ( "/gogs/" => "/" ) )
    }
    ```

    Set the matching external URL in `custom/conf/app.ini`:

    ```ini
    [server]
    EXTERNAL_URL = http://example.com/gogs/
    ```
  </Tab>
</Tabs>

## IIS

Create a new website in IIS and use the following `web.config` file.

<Note>
  If you do not need HTTPS handled by IIS, remove the entire `RedirectToHttps` rule section from the configuration below.
</Note>

```xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="RedirectToHttps" stopProcessing="true">
                    <match url=".*" />
                    <conditions>
                        <add input="{HTTPS}" pattern="off" ignoreCase="true" />
                    </conditions>
                    <action type="Redirect"
                            url="https://{HTTP_HOST}{REQUEST_URI}"
                            redirectType="Permanent"
                            appendQueryString="false" />
                </rule>
                <rule name="ReverseProxyInboundRule" stopProcessing="true">
                    <match url="(.*)" />
                    <action type="Rewrite"
                            url="http://localhost:3000/{R:1}" />
                </rule>
            </rules>
            <outboundRules>
                <rule name="ReverseProxyOutboundRule"
                      preCondition="ResponseIsHtml">
                    <match filterByTags="A, Form, Img"
                           pattern="^http(s)?://localhost:3000/(.*)" />
                    <action type="Rewrite"
                            value="http{R:1}://gogs.example.com/{R:2}" />
                </rule>
                <preConditions>
                    <preCondition name="ResponseIsHtml">
                        <add input="{RESPONSE_CONTENT_TYPE}"
                             pattern="^text/html" />
                    </preCondition>
                </preConditions>
            </outboundRules>
        </rewrite>
    </system.webServer>
</configuration>
```

Then set the matching external URL in `custom/conf/app.ini`:

```ini
[server]
EXTERNAL_URL = https://gogs.example.com/
```

## Native HTTPS

If you are not using a reverse proxy, Gogs can serve HTTPS directly. Update the `[server]` section of `custom/conf/app.ini`:

```ini
[server]
PROTOCOL  = https
EXTERNAL_URL = https://gogs.example.com/
CERT_FILE = custom/https/cert.pem
KEY_FILE  = custom/https/key.pem
```

| Option | Description | Default |
|--------|-------------|---------|
| `PROTOCOL` | Set to `https` to enable native TLS. | `http` |
| `CERT_FILE` | Path to the TLS certificate file (PEM format). | `custom/https/cert.pem` |
| `KEY_FILE` | Path to the TLS private key file (PEM format). | `custom/https/key.pem` |
| `TLS_MIN_VERSION` | Minimum TLS version. Options: `TLS10`, `TLS11`, `TLS12`, `TLS13`. | `TLS12` |
