Multiplayer mode in Terraria opens up completely new horizons for world exploration, construction and boss battles. However, in order for friends to join your game, you need to set up your network connection correctly. One of the key parameters in this process is the port number through which data is exchanged between devices.
On the platform Android this process has its own nuances that differ from the PC version. Many users encounter difficulties when trying to start a hosting server, not understanding which address and port to specify in the settings. In this material, we will look in detail at how to find this data and ensure a stable connection for your company.
Incorrect network configuration often leads to connection errors or an endless search for a server. Understanding how the local network works and what ports the game uses will help you avoid these problems. We will look at both standard values and ways to change them in case of conflicts.
Standard network settings of the game
By default, the game Terraria uses a certain range of ports to organize multiplayer. This is done in order to simplify the connection process for most users who do not require deep knowledge of network protocols. Knowing these values is the first step to successful setup.
The main port that the server uses Terraria, has number 7777. It is this number that must be specified when connecting friends, if you have not changed the settings manually. The data transfer protocol in this case is TCP/UDP, which ensures reliability and connection speed at the same time.
It is important to note that on mobile devices running Android these settings are often hidden from the user until a world with multiplayer support is created. The system automatically reserves this port when the hosting function is activated. However, if your device is already running another application that uses this port, manual intervention may be required.
⚠️ Warning: If port 7777 is occupied by another process, the game may not start the server or may throw an error when trying to connect. In this case, you will need to change the port number in the configuration.
To check whether the port is occupied, you can use third-party network analysis utilities available in Google Play. They allow you to see a list of active connections and used ports in real time. This will help diagnose conflicts before the start of the gaming session.
Before starting the server, close all background applications that may use network resources to avoid port conflicts.
Setting up a host server within the application
The process of activating the server directly in the game interface is quite simple, but requires attention to detail. You need to create a new world or select an existing one, making sure it supports multiplayer mode. In the world selection menu, pay attention to the corresponding icons.
After loading the world, go to the pause menu and select the option Settings. In this section you need to find the item responsible for the network connection. It is usually called Host & Play or similar, depending on the localization version Terraria on your device.
- 📱 Make sure your device is connected to a stable network Wi-Fi.
- 🌐 Check that you have permission to use the local network in the settings Android.
- 🔒 Disable temporary traffic restrictions for the game in the battery settings.
- 🎮 Select a game mode that allows other players to join.
When the server is running, information about connection. In some versions of the game, the IP address and port are shown in the lower corner of the screen or in the system chat. Make a note of this information, as your friends will need it to log in.
If automatic display is not available, you will have to refer to the router settings or use the command line on a connected PC to find out the details. On a pure Android without root access, viewing active network listeners is difficult, so the standard value serves as a guide.
Determining the local IP address of the device
In order for friends to connect to your server, they need not only a port, but also your local one IP address. Within a home network, each device receives a unique identifier, which looks like a series of numbers separated by dots. Without this address, connecting from outside is impossible.
You can find out your IP address on Android through the system settings. Go to the Settingssection, then select About phone or Status. In the list of parameters, find the item IP address. Depending on the smartphone model, the path may differ slightly, but the essence remains the same.
An alternative way is to go to the Wi-Fi connection settings. Click on the name of your current network and expand additional options. The IP address issued by the router will be indicated there. Most often it starts with 192.168. or 10.0..
| Parameter | Default value | Where to find |
|---|---|---|
| Game port | 7777 | Server settings |
| Protocol | TCP/UDP | Network settings |
| Local IP | 192.168.x.x | Wi-Fi settings |
| Max. players | 8 | Host menu |
Remember or write down this address. It is the combination IP:Port (for example, 192.168.1.5:7777) that is entered by friends in the connection field. An error in even one digit will result in connection failure.
⚠️ Attention: The local IP address may change after rebooting the router or device if static addressing is not configured. Check the current data before each gaming session.
Forwarding ports for connecting from the Internet
If you want to invite friends who are not on your home network, simply specifying a local IP will not be enough. You will need to configure the Port Forwarding (port forwarding) function on your router. This will open access to your device from the global network.
First, you need to log into the control panel of the router. This is usually done through a browser by entering the gateway address (often 192.168.0.1 or 192.168.1.1). The login and password are most often indicated on a sticker on the bottom of the device or in its documentation.
In the router interface, find the section responsible for port forwarding. It may be called Virtual Server, Port Forwarding or NAT. You need to create a new rule specifying your phone's internal IP and port 7777. Protocol select TCP/UDP or Both.
☑️ Setting up port forwarding
After saving the settings, the router will redirect all requests coming to port 7777 from the Internet directly to your smartphone. This is a critical stage for organizing a game with friends from other cities.
It is worth considering that some providers use technology CGNATthat hides users behind a common external address. In this case, port forwarding on your home router will not work, and you will need to contact your provider or use alternative connection methods.
Use of third-party network utilities
Sometimes the built-in tools Android are not enough for detailed network diagnostics. In such cases, specialized applications from the store come to the rescue. They allow you to get a more complete picture of your network environment and identify hidden problems. Google Play. They allow you to get a more complete picture of your network environment and identify hidden problems.
Applications like Network Analyzer or Fing are able to scan your local network and show all connected devices, their IP addresses and open ports. With the help of such tools, you can make sure that the port Terraria is really open and is being listened to by the system.
In addition, some utilities allow you to test connection speed and ping to various nodes. For online games, low ping is critically important, since high latency leads to “lags” and desynchronization of player actions.
How to check the openness of a port online?
There are web services that allow you to check the availability of a specific port of your external IP. Enter port number 7777 on such a site, after starting the server in the game. If the service shows that the port is open, then the forwarding configuration is done correctly.
Using such tools also helps identify the presence of third-party software that may be blocking the connection. Firewalls or antivirus apps at the router level sometimes mistakenly classify game traffic as suspicious.
Solving common connection problems
Even with proper configuration, failures can occur. One of the common reasons is the Windows firewall on a friends PC if they play from a computer, or the security settings on themselves Android. Make sure that the game is added to the exceptions of all protection systems.
Another problem is the incompatibility of game versions. All session participants must use the same version Terraria. Developers regularly release updates, and even a minimal discrepancy in the version number can make connection impossible.
If the connection fails after a certain time, check the power saving settings on your phone. The system may try to disable the Wi-Fi module or limit background game activity to save battery power, which leads to a disconnection.
⚠️ Attention: Router interfaces and Android settings are constantly updated. The location of menu items may differ on different device models and firmware versions. Check the current documentation of your equipment.
In case of persistent errors, try rebooting the router and all client devices. This clears the network table cache and often resolves problems with stuck connections. It’s also worth trying to change the Wi-Fi channel if there is too much interference from neighboring networks on the air.
The stability of the connection in Terraria on Android directly depends on the quality of the Wi-Fi signal and the correct setting of port forwarding on the router.
Frequently asked questions
Can I play Terraria on Android with players on PC?
Unfortunately, this is not possible directly. The mobile version Terraria and the PC version have differences in code and controls, so cross-platform multiplayer between them is not officially supported. You can only play with mobile device users (iOS and Android).
What to do if friends see the server, but cannot log in?
Check whether the game version is the same for all participants. Make sure the world is not set to Invite Only if you are not using this feature. Also check if the antivirus is blocking the connection.
Do you need a static IP for your phone?
For playing within a local network, this is not necessary, but it is advisable. To play over the Internet (with port forwarding), it is highly recommended to assign the local IP address to the phone in the router settings so that it does not change after a reboot.
Why does the game crash when trying to create a server?
This may be due to a lack of RAM or a port conflict. Try closing other applications. If the problem persists, check the integrity of the game files or reinstall it.
