How to fix Roblox Error Code 279

Got Error Code 279 on Roblox? Read the article on how to fix it

Released in 2006, Roblox has attracted a considerable player base during the 2010s. The game’s key selling point is the players’ ability to design their own games and play games created by others via multiplayer.

Roblox is a unique product as it allows users to program their games and play games created by other users. Roblox hosts multi-genre games created by its users coded in the Lua programming language.

For most of Roblox’s history, it was a small platform. However, its growth in popularity picked up during the second half of the 2010s. Most recently, its popularity began to grow rapidly during the year 2020. As of August 2020, Roblox had over 160 million monthly active users.

Roblox is free to play with in-game purchases available via a virtual currency called “Robux”.

As Roblox is not necessarily a game but a platform for creating games, let’s take a look at what games have been made on it. As of May 2020, the most popular Roblox games have over 20 million monthly active users each. Some of the more notable games include Adopt Me!, an MMO RPG averaging 600,000 concurrent players, and Jailbreak, a cops and robbers game played a total of 4 billion times as of August 2020.

Other games worth mentioning include MeepCity, Murder Mystery 2, Natural Disaster Survival, Piggy, Welcome to Bloxburg, and Work at a Pizza Place.

With its recent explosion in popularity, Roblox has not only attracted gamers and game creators but also exposed an issue users encounter when trying to play it. Many users have complained about getting Error Code 279. For players looking to hop into a game, this error presents a severe obstacle as it prevents them from connecting to a server.

Error Code 279 indicates that there’s a connection issue that prevents you from accessing a game. After failing to connect to a server, the game will present you with a window that says, “Failed to connect to the Game. (ID=17: Connection attempt failed.) (Error Code: 279.)

So what are the possible causes for Error 279? So far, Roblox players have discovered four possible reasons for it. Let’s go into these reasons in more detail.

The first possible reason could be a slow or unstable Internet connection. When the connection is slow, connecting to a server with large objects takes much longer than usual, resulting in a connection timeout that manifests as Error Code 279.

If a slow or unstable Internet connection is the cause of this error for you, then the first thing you ought to do is reset your Internet connection. Unplug your Internet router and turn off the devices connected to it.

The second reason is due to the Windows Defender Firewall blocking Roblox connections. If that’s the case, then you may get Error 279.

The third reason has everything to do with scripting objects in the game that may be too much for the game to handle. If you get Error 279 only on a few servers, then the issue lies with the servers.

The fourth reason why you may get Error 279 is if you run Roblox on an unsupported web browser. Many Roblox players solved this issue by launching Roblox on Google Chrome. However, it would help if you also tried running it on Microsoft Edge or Mozilla Firefox.

However, it’s not always the fault of the web browser. There have been reports that specific browser extensions, particularly adblockers, cause Error Code 279 to occur. Since Roblox’s launcher features ads, it’s plausible that blocking the ads will deny you the ability to connect to its servers. So Before switching browsers, try disabling some or even all of your browser extensions and see what happens.

Lastly, you may be unable to connect to a Roblox server due to your device not opening the required ports for Roblox. To fix this, you have to log in as an administrator to your router and add Roblox PC ports UDP: 49152–65535.

It has been determined that Error Code 279 occurs due to a connection issue, but its reason differs in each case. We have compiled a list of fixes that include temporarily turning off the Windows Defender Firewall, disabling your web browser extensions, and reinstalling Roblox.
