Network - Reverse Proxy

This guide will show you how to set up a reverse proxy for your Minecraft server. We will use Cloudflare in this example, but the steps will be similar for any domain provider.

With a reverse proxy, you can redirect HTTP traffic from a specific domain (e.g., squaremap.example.net) to the correct port on your server, making it easier for users to access specific resources, like a Minecraft map plugin. It is important to note that this method does not apply to the game itself; you will need to set up an SRV record. See Use a Custom Domain or Subdomain for instructions.

You must have purchased a domain name from a domain registrar before continuing and have your server's IP address ready to be used.

Access the Cloudflare Dashboard

For this guide, we will use Cloudflare as an example. The instructions may be different for other domain service providers. Always refer to your specific provider.

Navigate to Cloudflare and log in to your account.

Navigate to DNS Settings

Click on the domain to configure.
Click on the 1 DNS option on the navigation bar.
Click 2 Records.

This is where you will create the A record required for the reverse proxy to function.

Create an A record

Click on 1 + Add record.
From the drop-down, select 2 A record.
In the 3 Name field, enter the subdomain you want to use.

For example, map if you are going to create map.ultraservers.com.

In the 4 Target field, enter the Server’s IP address.

For the sake of this guide, we’ll use 149.40.59.139.

Disable 5 proxy status.

This step is specific for Cloudflare, so you may ignore it if it's not applicable. We do not want Cloudflare to proxy any traffic; otherwise, the reverse proxy will not work.

6 Click on Save.

Create the Proxy

Log in to the panel. See Access the Panel for instructions.
Go to the 1 Network tab.
Click the 2 Proxy tab.
Click the 3 Create Proxy button.

Configure Proxy

1 In the pop-up, enter the entire domain you set up in Cloudflare.

For example, map.ultraservers.com.

Toggle Enable SSL to create a certificate for this proxy.

(Optional) Toggle Use Let’s Encrypt to generate an SSL certificate via Let’s Encrypt.

Click on the Allocation drop-down and select the 2 port you want to reverse proxy for.
Click 3 Create.

Check your Setup

When you navigate to the proxy domain, you should see your web app without the port.
