Fixing is not the only thing associated with this issue. Let me say what I personally felt. Error code 279 is not a rare Roblox disease, and you may face it multiple times. First, you should know the causes. It will help you to solve the issue, and at the same time, it will help to prevent the issue from happening again. 

Fixing the Roblox Error Code 279 can be tricky, but there are actions you may do to try to fix the problem. Finding the reason for the error code is the first step.

Firewall issues: Numerous cases of firewalls blocking Roblox caused the “Error Code 279” on Roblox. A firewall protects a device from harmful agents like viruses, malware, etc. It, therefore, blocks signals from apps it considers harmful. However, at certain times, firewalls are known to misidentify Roblox as a harmful app and thus block the signals coming from the game servers. This can lead to “Error Code 279” on your device. 

An error by Developers: You can encounter empty games while playing Roblox which can cause the “Error Code 279” in your game. Empty games are games where the developers forget to add or delete items from the game, making it empty. 

Also, when a developer launches new updates or game modes, there may be some bugs or glitches in the mode. These bugs and glitches can disrupt the connection between the game and the servers, which can lead to “Error Code 279” on Roblox.

Internet connection fluctuation: Lastly, a faulty internet connection may be a reason for “Error Code 279” on Roblox. This is because Roblox is a very big game with many game modes and numerous items. So, if you own a large variety of assets in the game, your game may have a fluctuating internet connection as the game needs to load a large number of files. This fluctuating internet connection may break your device’s connection with the game server, causing an error. Also, you can experience the error if you have an unstable internet connection due to network issues.

All The Possible Solutions Of Roblox Error Code 279

There are several solutions available when it comes to fixing the Roblox Error Code 279. Regardless of your level of experience, these solutions can help you get back into your favorite games quickly and easily. Here are some of the best solutions for solving this problem:

One of the first tricks you can try to resolve the “Error Code 279” issue on Roblox is opening the game on a different browser. There are two reasons for this step. 

Firstly, the browser that you are using might be unreliable. They may contain certain bugs and viruses that are leading to the error. Secondly, your browser may not be up-to-date. This can cause issues for Roblox because Roblox always keeps on publishing new updates, which can make the game inaccessible on outdated internet browsers. 

This is why you need to open the game on a different reliable browser like Chrome or Bing and ensure that the browser is the latest version available.

Disable Windows firewall

Disable Windows Firewall

While windows firewall is vital software to protect your device from harmful agents, it is still important to disable it if it is causing “Error Code 279” on Roblox. Firstly, try to disable it and check whether the game is functioning temporarily. If not, then to disable the windows firewall permanently, follow these instructions:

  1. Go to Windows Defender Firewall after typing in the “Search” option.

Disable third-party browser extensions

Third-party extensions can be another important reason for “Error Code 279” on Roblox. Roblox generates most of its income through ads on its games. However, many players try to use extensions like ad-blockers to remove the ads from their game. This can have a negative impact since the Roblox developers are against this practice, and they can block your Roblox account. This can cause an error issue on Roblox. So, it is optimal to uninstall any ad-blocking extensions from your device.

Also, many players prefer to use cheat engines and other third-party software to gain certain advantages in the game. This can have the same effects as ad-blocking extensions and, therefore, can cause “Error Code 279” on Roblox. So, to make sure that the error issue is settled, you also need to uninstall any cheat engines or other third-party software from your device.
