what is the Roblox Error Code 279 and how to fix

There are multiple reasons why you are getting this particular error. These connection issues that are seeing could be due to the following reasons:

  • Your internet connection is slow.
  • Windows Firewall is causing it.
  • Roblox is going through downtime.
  • Your Browser Extensions are causing issues.
  • Your Antivirus is blocking it.
  • Range of Ports is not open on your network.

Let’s take a look at each of them in some detail.

Internet Connection

Since this is a connection related issue, first ensure that your internet is working properly. If there is a significant drop in the connectivity, you will see this error code. So one solution is to check your net speed beforehand or upgrade to a high speed pack.

Windows Firewall

Such issues are most likely caused by the Windows Firewall. You can solve it by giving all the necessary permissions for Roblox. Because if you don’t, the Firewall will block it and pop up this error. Once you allow Roblox to bypass restrictions, you should be able to connect right away.


Although not a frequent thing, there could be a chance that Roblox is going through downtime. Make sure to check social media sites for any updates about server maintenance or server overload. When you see that most people online are talking about it, you can rest assured that you are not the online one getting this error.

Browser Extensions

Check if any Browser extensions are causing issues while connecting to Roblox games and disable them. Also note if the Browser is supported by Roblox and that it is updated to the latest version. Chrome and Firefox are the best options to use the web version of Roblox.


Sometimes, your Antivirus software can block you from connecting to a Roblox game and can show you the Error Code 279. What you can do is temporarily disable it until you are playing and enable it after that. You can also make Roblox an exception in your Antivirus software.

Port Forwarding

This is a bit technical but it could be one of the reasons why you are not able to connect. In simple terms, you can try “Port Forwarding” where you have to set the range of ports. Here’s how to do it:

  • Open the Router control panel.
  • Make sure to login to it as the Admin.
  • Go to Port Forwarding.
  • Put your IP address.
  • Input UDP 49152 65535 as the port range and choose UDP as the protocol.
  • After all this, you have to restart the router and start Roblox.
