 Minecraft requires the use of an ngrok TCP tunnel to share your server with others. Use `ngrok tcp 25565` to open a TCP tunnel on the default Minecraft port. You can then use the address provided to connect to your Minecraft server.
 
-The free version of ngrok does not allow you to get a permanent TCP address, which means when you restart the agent, you will need to send a new TCP address to your players. Our paid accounts allow you to reserve a TCP Address for reuse. In this case, you would start the TCP tunnel using `ngrok tcp --remote-addr TCP_ADDRESS 25565`.
+The free version of ngrok has the following restrictions:
 
-CAUTION: The TCP tunnel you open is available to anyone by default. Our paid accounts allow you to restrict access to specific IP Addresses using IP Restrictions.
+- **No permanent TCP address**
+  - When you restart the agent, you will need to send a new TCP address to your players. Our paid accounts allow you to reserve a TCP Address for reuse. In this case, you would start the TCP tunnel using `ngrok tcp --remote-addr TCP_ADDRESS 25565`.
+- **Bandwidth Limits**
+  - The free plan includes a limited amount of bandwidth per month which will prevent players from connecting to your server when exceeded.
+- **No IP Restrictions**
+  - Your Minecraft server will be available to anyone by default.
+
+Static/unchanging addresses, increased bandwidth limits, and IP Restrictions are all available with our [paid accounts](https://ngrok.com/pricing).
+
+## Troubleshooting
+
+### Bandwidth Limit Exceeded
+
+If you exceed the bandwidth limit on your account players will no longer be able to connect to your server.
+
+Players attempting to connect to your server may see a "Disconnected" message in the Minecraft client.

+Your server logs may indicate the client connecting and immediately disconnecting.
