Roblox creates a cache and logs files in order to reduce the loading time of the game every time. But sometimes, this cache and logs can get corrupted due to some external factors and can lead to Roblox Error Code 279. There are two locations in which these files are stored.

To delete the roblox log files:

  1. Open the Run box by going into your Search bar in your bottom left of your computer or by pressing the Win + R key.
  2. Now enter %localappdata%\Roblox\logs in the Run dialog box.

5. Allow Firewall

A firewall is a windows feature that blocks the access of certain spammy IPs and domains. This windows feature has prevented many users from getting scammed online. But sometimes this application can block the IPs of many games unknowingly hoping they are spammy. So, we need to whitelist our Roblox game in order to play it smoothly every time. Whenever the firewall refused the Roblox connections, you can get disconnected by throwing a Roblox error code 279.

To allow Roblox in Firewall –

  1. Open the Windows Search bar from the bottom left side of your screen and enter Control Panel in it to open the new window.
  2. Now among the many options, carefully select the Windows Defender Firewall option. This will open your Firewall settings.

  5. Now tick the checkboxes stating to allow both public and private networks.
  6. Lastly, apply the changes and restart your computer.

This will make sure your Firewall don’t interfere with Roblox connections.

6. Change Internet Service Provider

If you’re unable to solve your connection error using the above steps. Then probably you are in bad luck. Your ISP might have banned the servers for Roblox over their network. ISPs do this very often to restrict their users from entering shady websites. Unfortunately, there is no current solution to this error. The only alternative to this is, change your ISP or inform your ISP to unblock these ports.

7. Reinstall Roblox

Corrupted installation of Roblox can also lead to Roblox Error code 279. This incomplete installation can occur due to many reasons, unavailability of RAM, failure of connection, and many more. This is the last hope to solve your error. If this step doesn’t solve your error then there is a problem in the Roblox Server itself.
