The Problem Explained

Unlike some other errors, including those we see on other platforms such as Steam and Twitch, the 279 Roblox Error is accompanied by a concise message, explaining the reason behind the error code.

The message users get when encountering this problem is the following:

Failed to connect to the Game. (ID = 17: Connection attempt failed.) (Error Code: 279)

Disconnected Error Code 279

By reading this message, users get at least some insight that the error is caused by something interfering with their connection. And, based on our research and time spent troubleshooting, we confirm that the error does indeed seem to be caused by a few key factors preventing a stable connection to Roblox servers.

Thankfully, there are a few solutions available. Here’s how to fix it.

Fix 1: Ensure You Have A Stable Internet Connection

Although most of us refuse to believe our internet connection is the cause of the error, it often turns out to be the truth.

“But, how was I previously able to play, and now I can’t, yet you’re telling me the connection can be the problem?” – you’re probably asking.

Well, the poor connection performance can be only temporal, and the best way to know for sure is by running a speed test. We recommend Speedtest by Ookla, as it is easy to use and requires just one click to get the necessary information.

If you notice your ping is way too high, or your upload/download speeds are way below average, contact your ISP for further clarity, as that is most likely the reason why you can’t connect to Roblox servers.

Other things you can do are stop any ongoing downloads and ensure the bandwidth is fully dedicated to your Roblox connection.

If the results come out normal, and you’re sure there’s no problem with your connection’s performance, move on to the other solutions listed below.  

Fix 2: Ensure Your Windows Firewall Isn’t Blocking Access To Roblox Servers

Your Windows Firewall is responsible for keeping your PC protected from any unwanted files when connecting to unknown servers and downloading things from the internet.

However, sometimes Windows Firewall is unable to distinguish safe from unsafe and blocks access to various games and services, one of which is Roblox.

To ensure this isn’t the case, add Roblox to your Windows Firewall’s list of exceptions, or temporarily disable it to see if you’ll be able to connect to a server.

If disabling it temporarily helps, add Roblox to the list of exceptions so that your PC remains protected from other threats, while still being able to play.

Here’s how to do that:

  1. Click on the Windows Search Box and type in Firewall & Network Protection. Press Enter on your keyboard to open the panel.
  2. Scroll down until you see the Allow an app through the firewall option, then click on it.
  3. Add Roblox to the list of apps your firewall should consider safe.

You can do the same thing with Windows Defender. Add Roblox to the list of exceptions to ensure it doesn’t block your access.

If this doesn’t work, move on to the next fix, which is disabling browser extensions

Fix 3: Disable Possibly-Interfering Browser Extensions And Add-Ons

Users reported that having extensions such as Ad-Block and uBlock Origin enabled on their browsers prevented them from establishing a stable connection with Roblox servers.

To ensure this isn’t the case, start disabling the extensions one by one, attempting to connect to a server after each one.

This will help you pinpoint the problem and find out which extension is causing the problem if the root of it is indeed a browser extension.

If not, there are more methods you can try.

Fix 4: Flush Your DNS And Perform Winsock Reset

This is a well-known and common fix for many other similar connection problems, such as the 279 Roblox error.

At first, it may seem daunting, but once you look at the step-by-step tutorial down below, you’ll understand how easy it is to flush your DNS and perform a Winsock Reset.

Here’s how to do it:

  1. Click on the Windows Search Box located in the bottom-left corner on your taskbar, and type in Command Prompt. Right-click the first result and select Run as Administrator.
  2. In the command prompt, type in the following commands, and press Enter on your keyboard after each one: ipconfig /flushdns and netsh winsock reset
  3. After you get the two returning messages saying Successfully flushed the DNS Resolver Cache and Successfully reset the Winsock Catalog, restart your PC for the changes to take effect.

The informative video below showcases the process, along with a few other helpful fixes, so feel free to take a look to get a further explanation of the steps listed above.

After your PC successfully reboots, start Roblox again and try connecting to a server. It should now work.

Fix 5: Add Roblox As An Exception In Your Antivirus Software

If you are using third-party antivirus software, and not just Windows Defender, it might be labeling Roblox as a potential threat, therefore preventing you from connecting to the server. To ensure this isn’t the case, temporarily disable your antivirus, or add Roblox to the list of exceptions.

Even some of the most popular antivirus programs are known to sometimes make mistakes, so make sure to try this before moving on to other solutions.

Fix 6: Try Connecting To Other Servers

Sometimes, the problem might be the server you’re trying to connect to, so it doesn’t make much sense to try and tweak anything on your end if the server is down or faulty.

To know whether or not this is the case, try connecting to a different game or a different server and see if that works. If you are able to get in, then the problem lies within the server you were previously trying to connect to.

In this case, it’s usually best to just wait until the server is back up and running, or simply choose to play a different game instead.


Now you know how to fix the infamous Roblox 279 Error, so feel free to apply this knowledge and overcome the problem so you can get back to playing carelessly.

Remember that Roblox also has a support team you can contact if you experience other problems while trying to connect or use their platform. Reaching out is strongly advised if you can’t seem to find another way around a specific problem.
