  • Packet Loss- The issue occurs when the transmitted data packets do not arrive at their destination, and the transferred data between the server and your computer is lost.
  • Latency Variance- If you have a high ping issue, the data generally takes milliseconds to transfer, but due to high ping, it can take more than 5 seconds to arrive, which can cause error code 42 means your game has lost the connection.
  • High Latency- High latency is known as “lag,” which means the computer takes a long time to send a bit of data to the remote server. High latency can also cause bottlenecks in communication and also might be the reason for error code 42.

Now we know the causes, let’s have a look into the potential solution.

Check the Server Status

Before getting into the solutions, we suggest you check the Rocket League server status from the official community or a website because sometimes the Rocket League server goes down. According to the Rocket league developers, the issue could occur when the servers are having some problems. For that reason, make sure to check the server status. If the servers are down, then wait until the servers get stable, but if it’s not, then move on to the other solutions that might help you resolve error code 42.

Check the Minimum Game Requirements

The low or end system specification can be the reason why your game loses the connection. According to the devs, if you do not meet the game’s minimum requirements, the error could occur because your game is not loading as fast as it should.

Generally, the Rocket League does not load correctly, and it can cause error code 42, so the best approach is to restart the game or console to ensure that the loading is not preventing you from playing the game.

Enable Port Forwarding

In most cases, rocket league ports can be blocked by the Router. A router connects to your ISP (Internet Service Provider). Inside that Router, the ports, also known as gateways, protect you while browsing the internet. Sometimes those gateways block the program it should not, like Rocket League and other programs.

Every Router setting is a little different, but we will guide you similarly to the other Router settings. If you run into problems, try searching your Router support website for more detailed info on port forwarding.

Note- If your network is private then this method will not work for you you can check your network status from here. Rocket League must be running on your system when you performed port forwarding, so the port can be seen as open during the check.

Follow the below steps to enable the port forwarding:-

  1. First, press the Windows key and type the command prompt in the search bar.
  2. Open the command prompt and insert the below command then press enter.
    ipconfig
  3. Here you should see the default gateway and the IPV4 address.

DNS servers can boost gaming performance by blocking malicious data. It also allows users to enjoy a smooth gaming experience by preventing nasty viruses from running applications on Windows.

Reset Network Settings

Use Ethernet instead Wifi (If possible)

There is no doubt the wifi connections have improved a lot, but for the accurate result or better gaming performance, we prefer to use an Ethernet connection instead of Wi-Fi. However, if you use a Wi-Fi connection, you might face problems like ping spikes and high latency when you play Rocket League. 

Add an Exclusion in Windows Defender

In most cases, the interference of the third-party software can prevent the game from running correctly, even though it can happen with the Windows defender.

Enable Proxy settings

If your internet speed is not good enough to run the game, you could use a proxy server as the last option. A proxy server allows the internet connection to speed up the performance and works as a gateway between the server and your system to hide your Ip address.

Using a proxy server might fix your error code 42. Below are the steps to enable the proxy server.

  1. Open the settings by pressing the Windows + I keys together.
  2. Click on the Network and Internet option.
  3. Click on Proxy on the left sidebar.
