Roblox Error Code 279: How To Fix It Quickly?

Were you excited to play your favorite Roblox game but are getting the Roblox error code 279 issue? Well, you are not alone, as complaints have been pouring in from gamers worldwide. This error prevents users from connecting to a game. In this article, we have listed all the steps that you can take to fix Roblox error code 279 completely. Also, we have written what the error means and why it occurs on your computer.

What Is The Roblox Error Code 279?

After investigating the error in detail, we concluded what it means. The error occurs when the game thinks you have a poor internet connection. Users with a poor internet connection can affect the server’s performance. And thus, the game doesn’t allow that. This happens because when your internet can’t keep up with the game. The server has to compromise.


Thus, to prevent this, game developers often cap the lowest quality of connection that can connect. Therefore, you will see the “Failed to Connect to the Game” error if your connection falls below that threshold.

Why Are You Getting The Roblox Error Code 279?

As seen above, the error triggers when you have a poor internet connection. Behind this, there can also be some other reasons that we will discuss below.

  • Internet Connection: The connection you are using must be of a certain quality. The game requires you to stream data at a particular speed. If your internet connection can’t do that, you will encounter issues.
  • Router Configuration: Sometimes, the router you use can get the wrong configurations. This happens when the router runs for an extended period without resetting. The router can get incorrect DNS configurations or be routed through the wrong path.
  • Windows Firewall: The Firewall on your device can prevent Roblox from connecting. This happens if the Firewall thinks that Roblox is making suspicious connections. To fix this, you can either turn off your Firewall or allow Roblox through the Firewall.
  • Browser Issue: The browser you use to play Roblox can also affect your game. This happens because all browsers have their specific security protocols. Some of these protocols can block certain aspects of the game. Thus, you should try to ensure that you are using compatible browsers.
  • Browser Extensions: Extensions are also known to cause issues every once in a while. Thus, you should ensure that your extensions are not interfering with any aspect of the game. To do this, you can try to turn off the extensions one by one and check which causes the issue with the game.
  • Closed Ports: The game communicates with its servers using ports. These ports are the game’s access points to connect to the servers. If the ports that the game requires are closed, it will get the Roblox error code 279. Thus, you should try to make sure that the ports are forwarded.
  • Game File Issue: If there is any damage to the game file integrity, an error will occur. The files can get corrupted over time, damaging their integrity. Thus, you can try to install a fresh copy of the game after removing it and adding it again.
  • DNS Cache: The DNS cache on your computer can also sometimes cause this issue. This DNS cache is created locally on your Windows computer. Thus, you can try to clear out the DNS and the Winsock.
  • APN Settings: The APN settings on your mobile device allow it to connect to the internet. However, they can prevent you from connecting to the internet if incorrectly configured. And cause the Roblox error code 279 on Android.

Now that you know why error 279 occurs, you can finally start implementing the solutions to fix it.
