There’s no doubt that Roblox is one of the most popular platforms for modern gamers and a great way to spend your free time when you’re feeling creative.
However, it is because Roblox is such a fun creation that being unable to access it can be particularly frustrating.
The 279 error is known for blocking users’ access to the platform. To make matters worse, it is also one of the most common issues, meaning your chances of being greeted by it during your Roblox adventures are relatively high.
This guide contains all the information you need to solve this problem and continue enjoying Roblox without further issues.

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 that explains the reason for the error code.
The message users see when encountering this problem is the following:
Failed to connect to the Game. (ID = 17: Connection attempt failed.) (Error Code: 279)
By reading this message, users gain at least some insight that the error is caused by something interfering with their connection. Based on our research and time spent troubleshooting, we can confirm that the error indeed appears to be caused by a few key factors preventing a stable connection to Roblox servers.
Thankfully, there are several possible solutions. Here’s how to fix it.
Fix 1: Ensure You Have A Stable Internet Connection
Many of us refuse to believe our internet connection could be responsible for errors, but it often turns out to be the case.
You might be asking how you were previously able to play but can’t anymore. What has changed?
Well, the poor connection performance might only be temporary. The best way to find out is by running a speed test. We recommend Speedtest by Ookla, as it is easy to use and only requires one click to get the necessary information.
If you notice that your ping is way too high, or your upload/download speeds are below what you expect, contact your ISP for more information, as that is probably why you can’t connect to Roblox servers.
Other adjustments you can make include stopping any ongoing downloads and ensuring your bandwidth is fully dedicated to your Roblox connection.
If the speed test results appear normal, and you’re sure there is 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 data 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 are able to connect to a server.
If disabling it temporarily helps, add Roblox to the list of exceptions so you can play while your PC stays protected against other threats.
Here’s how to do that:
- Click on the Windows Search Box and type in Firewall & Network Protection. Press Enter on your keyboard to open the panel.
- Scroll down until you see the Allow an app through the firewall option, then click it.
- Add Roblox to the list of apps your firewall should consider safe.
You can do the same 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 Potentially 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, disable the extensions one by one and attempt to connect to a server after each one.
This will help you pinpoint the problem and find out which extension is causing the issue if the origin 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 reliable fix for many similar connection problems, such as the 279 Roblox error.
It might initially seem daunting but once you look at the step-by-step tutorial below, you will see how easy it is to flush your DNS and perform a Winsock Reset.
Here’s how to do it:
- Click on the Windows Search Box located in the bottom-left corner of your taskbar, then type in Command Prompt. Right-click the first result and select Run as Administrator.
- In the command prompt, type in the following commands, and press Enter on your keyboard after each one: ipconfig /flushdns and netsh winsock reset
- After you see 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 describes the process, along with a few other helpful fixes, so take a look for 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 flagging Roblox as a potential threat, thus 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 occasionally make mistakes, so be 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. There is no point in trying to tweak anything on your end if the server is down or faulty.
To determine 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, the problem lies with the server you were previously trying to connect to.
In this case, it’s usually best to simply wait until the server is back up and running, or simply play a different game instead.
You now know how to fix the notorious Roblox 279 error, so go ahead and apply this knowledge to overcome the problem and get back to playing normally.
Remember that Roblox also has a support team you can contact if you experience any problems while trying to connect or use their platform. We strongly recommend reaching out to them if you can’t seem to find another way around a particular problem.
