Arma 3 Host Server Not Working: A Comprehensive Guide for Dev

Hey there, Dev! Are you struggling with your Arma 3 host server not working? If so, you’re not alone. Many gamers and server hosts have encountered similar issues that prevent them from enjoying the game.

However, don’t worry. In this article, we’ll explore the most common reasons why your Arma 3 host server is not working and offer you practical solutions to fix them. So, let’s dive in!

1. Check Your Server’s Network Settings

The first step to fix your Arma 3 server issue is to check your server’s network settings. Ensure that your server is properly configured with the right IP address, subnet mask, and gateway. This information is critical to connect your server to the internet and, therefore, to allow players to join.

You can verify your server’s network settings by accessing the server’s control panel and checking the network configuration options. If everything looks fine, but you’re still unable to connect, move on to the next step.

2. Check Your Server’s Firewall Settings

The second reason why your Arma 3 host server may not be working is because of your server’s firewall settings. Firewall applications are designed to protect your server from malicious attacks and hacking attempts, but they may also block legitimate traffic to your server, including Arma 3 connections.

To fix this issue, you can either disable the firewall temporarily or add an exception for Arma 3 traffic. Disabling the firewall completely is not recommended, so we suggest you add an exception for Arma 3 traffic instead.

How to Add an Exception for Arma 3 Traffic in Windows Firewall

1. Open the Windows Control Panel.
2. Click on Windows Defender Firewall.
3. Click on Allow an app or feature through Windows Defender Firewall.
4. Click on Change settings.
5. Click on Allow another app.
6. Browse and select the Arma 3 executable file.
7. Click on Add.
8. Select both Private and Public checkboxes.
9. Click on OK.

3. Check Your Server’s Ports

The third reason why your Arma 3 host server may not be working is because of your server’s ports configuration. Arma 3 uses several ports for communication, and if any of them are blocked or misconfigured, you may experience connection issues.

You can check your server’s port configuration by accessing the server’s control panel and reviewing the network settings. Ensure that the following ports are open and forwarded to your server:

Port	Description
2302 (UDP)	Main game port
2303 (UDP)	Steam query port
8766 (UDP)	Steam master server port
27016 (TCP)	Steam server browser port
80 (TCP)	HTTP port
443 (TCP)	HTTPS port

4. Check Your Server’s Hardware Configuration

The fourth reason why your Arma 3 host server may not be working is because of your server’s hardware configuration. If your server does not meet the minimum requirements to run Arma 3, you may experience performance issues or crashes.

Ensure that your server meets the minimum requirements to run Arma 3. According to Bohemia Interactive, the minimum requirements are:

• OS: Windows 7 SP1 (64-bit) or later
• Processor: Intel Dual-Core 2.4 GHz or AMD Dual-Core Athlon 2.5 GHz
• Memory: 4 GB RAM
• Graphics: NVIDIA GeForce 9800GT or AMD Radeon HD 5670 or Intel HD Graphics 4000 with 512 MB VRAM
• DirectX®: 10
• Hard Drive: 32 GB free space

5. Check Your Server’s Mods and Add-ons

The fifth reason why your Arma 3 host server may not be working is because of your server’s mods and add-ons. If any of your mods or add-ons are incompatible or outdated, they may cause issues with your server’s performance or connectivity.

To fix this issue, you can either update or remove the mods and add-ons causing the issue. Ensure that all your mods and add-ons are compatible with the latest Arma 3 version and that they do not conflict with each other.
