Updated: How to Deal with Roblox Error Code 277

Lego-like games such as Roblox and Minecraft have become popular because they offer players with lots of creative freedom. Roblox, in particular, not only allows players to explore thousands of online worlds, but also enables them to create and customize their own worlds.

Roblox is a free brick-by-brick game with more than 64 million active players every month. It is the largest social platform where gamers can create, play, and interact with other players. All you need to do is sign up for a Roblox account, create your persona, and enjoy the game!

Roblox is a game for kids of all ages and is available for Android, iOS, Windows, macOS, and Xbox. Some gamers prefer to play it on mobile phones because of mobility advantage, while others prefer the wider screen of Windows and macOS devices, which allows them to see the game in full detail.

However, Roblox is no perfect game. One of the most common Roblox issues is the error code 277. This error occurs randomly and has been the cause of frustration for a number of Roblox users.

What Is Roblox Error Code 277?

The Roblox error 277 has likely left affected players annoyed, especially since the developer has not issued any official fix yet. The error can happen on mobile devices and gaming consoles, but is more common on Windows and macOS devices.

The error 277 can happen when you’re trying to join the game or in the middle of one, and is usually accompanied by this error message:


Lost connection to the game server, please reconnect (Error Code:277)

When you get this error, you can choose to Leave or Reconnect the game. However, trying to reconnect is pointless because it just brings up the same error repeatedly.

It is not clear what the exact cause of the error is, but several players associate it with poor internet connection, particularly Wi-Fi issues. Some users also believe that the issue is connected with the port being used by the router to connect to the game.

The error could also be caused by server failure on Roblox’ side, which means the user can’t do anything except try to reconnect again or switch to a different server. Roblox is already aware of the issue and the team is working on a solution, but a lot of users are still experiencing Roblox error code 277.

One thing’s for sure: the reason for error 277 happening is not the same for everyone. Internet connection, corrupted system files, malware infection, and incomplete installation files can all lead to Roblox error 277. This is why we’ve come up with this troubleshooting guide to help you resolve this problem. We’ll take a look at these common causes of this Roblox error and list down the steps needed to fix it.

How to Fix the Roblox Error Code 277

Before doing any troubleshooting on your computer, make it a habit to do a basic computer checkup first to ensure no other issues are at play. These first-aid steps include rebooting your system, cleaning up your computer using an app such as Outbyte PC Repair, and plugging in your charger in case the process takes too long.

You also need to make sure your device meets the minimum hardware and internet speed requirements for Roblox. To be able to play Roblox smoothly, you will need:

  • A Windows 7, Windows 8/8.1, or Windows 10 PC. If you’re using Windows 8/8.1, you need to launch Roblox in Desktop Mode because Metro Mode is not currently supported.
  • DirectX 9 minimum and Shader Model 2.0
  • CPU 1.6 GHz or better, 1GB RAM, and at least 20 MB of system storage space
  • Minimum 4-8 Mb/s internet connection or higher

After doing these emergency steps and making sure you meet the minimum hardware and internet requirements, you can then proceed with the fixes below.

Solution #1: Run Roblox in Compatibility Mode.

Roblox usually works well with Windows 10, but compatibility issues could crop up sometimes and mess with your game. Most apps like Roblox that were created for previous versions of Windows are likely to encounter issues when running on the new operating system.

There are two ways to fix compatibility problems on Windows: changing the compatibility mode settings or using the built-in Program Compatibility Troubleshooter.

Follow the steps below to edit Roblox’ compatibility mode settings:

  1. Right-click on the Roblox app shortcut and choose Properties.
  2. Click on the Compatibility tab, and then tick off Run this program in compatibility mode for.
  3. In the dropdown menu, choose the Windows version you want to use for your app’s settings.
  4. Click the Apply button.

Run Roblox using these settings to see if it fixes the issue. If not, you can try running the Program Compatibility Troubleshooter by using the instructions below:

Click Start and search for run programs.

  1. Click on Run programs made for previous versions of Windows from the search results.
  2. Click the Next button to run the troubleshooter and scan potential compatibility issues with your apps. Once the diagnosis is complete, you’ll see a list of apps you’re having trouble with.
  3. Look for Roblox from the list, click on it and then hit the Next button.
  4. Choose the troubleshooting option you want to use. You can either use the recommended compatibility settings or choose the compatibility settings yourself based on your specific concerns.

Follow the troubleshooting instructions, the click the Test the program button to see if the problem has been resolved.

Solution #2: Delete Roblox Logs.

Roblox stores temporary data such as game history, settings, and other files that could take up considerable space on your computer. These files could also cause glitches or issues when you’re running the app, so you should regularly clean up these temporary files to avoid errors.

To delete the Roblox app’s log files, follow the steps listed below:

  1. Press Windows + R keys to launch the Run dialog.
  2. Type in the following directory name in the dialog box, then press Enter:
    • %localappdata%\Roblox\logs
  3. Press Ctrl + A to select all the files in the folder, then press Shift + Delete to completely delete them.
  4. Open the Run dialog once again and go to this folder:
    • %USERPROFILE%\AppData\LocalLow\RbxLogs\
  5. Repeat step 3.

Try running Roblox again to check if this solution has fixed Roblox error 277. Take note that deleting the game logs will also delete all your saved games and previous settings, so you’ll have to start over again.

Solution #3: Switch to a Different Network.

If you’re getting the error code 277 when playing Roblox, it might be related to the ports your router is using. Some users reported getting the error when connected to a particular network, such as their home Wi-Fi, but disappears when they switch to a different network. If you’re using your home or office network for playing, try switching to mobile data to see if it works. If it is, you might need to reconfigure the ports on your router, which will be discussed below.

Solution #4: Change Opened Ports on Your Router.

Before 2018, the default UDP port range for Roblox was 1025-5000. After the 2018 update, the default range became 49152 – 65535. To change the opened ports on your router, follow the steps below:

  1. Find your router’s IP address by clicking Start > Settings > Network & Internet > View your network properties. Your router’s IP address is the one next to Default Gateway.
  2. Open your browser and type in the IP address to access your router’s settings page.
  3. Type in your username and password.
  4. Click on the Port Forwarding section. Each router’s settings page is different, so if you don’t see the Port Forwarding section, look for any of the following options or their variations:
    • Applications
    • Gaming
    • Virtual Servers
    • Firewall
    • Protected Setup
    • Advanced Settings
  5. Once you’ve opened the Port Forwarding section or its equivalent, open your preferred port range by filling out the required information:
    • Name/Description– Type in Roblox.
    • Type/Service Type– Enter UDP.
    • Inbound/Start– Type in 49152.
    • Private/End– Type in 65535.
  6. Next, enter your computer’s private IP address.

Click the Save or Apply button to save your settings, then restart your router for the changes to take effect. Disconnect your computer from your router, then reconnect to see if the Roblox error still exists.

Solution #5: Update Your Browser.

If you’re not using the most updated version of your browser, it is possible that you might run into problems like Roblox error code 277. If you’re playing Roblox Studio, you will need to have the latest version of Internet Explorer for the game to work perfectly. You also need to make sure that the security settings of your browser allow Roblox. If your security settings are too high, errors like this might happen.

While you’re at it, disable any ad-blocker or browser extensions you might have installed on your browser. These add-ons can prevent Roblox from fully loading and causing errors.

If you’ve updated your browser and you’re still experiencing issues, try playing the game using a different browser. Roblox is compatible with most major web browsers, such as Google Chrome, Microsoft Edge, Mozilla Firefox, Internet Explorer, and Safari.

Solution #6: Reset Internet Options Using Internet Explorer.

If the above solutions don’t work, resetting Internet Options under Internet Explorer might help. To reset your Internet Options, you will need to run Internet Explorer. However, you don’t have to worry because this method will reset the internet settings for all your browsers, including Firefox and Chrome.

To do this:

  1. Launch Internet Explorer. Make sure IE is updated to the latest version.
  2. Click the gear icon, then choose Internet options.
  3. Click on the Advanced Tab.
  4. Clock the Reset button.
  5. Close Internet Explorer and try playing Roblox again.

Solution #7: Turn Airplane Mode On and Off (Mobile Only).

If you’re using a mobile device to play Roblox and encounters error code 277, here’s a quick fix that works:

  1. Close all running apps on your device.
  2. Depending on the mobile device you are using, swipe up or down to reveal the quick settings.
  3. Tap the Airplane Mode icon to turn it on. This should disable and reset all your network connections.
  4. Wait for a few seconds, then tap the Wi-Fi icon to turn it on.
  5. Launch Roblox and resume playing.

Solution #8: Reinstall Roblox.

If doing all the steps above don’t yield positive results, your last option is to remove Roblox from your computer and reinstall a clean version. This would also help if you’re getting the error code 277 due to failed or incomplete installation. Reinstalling will overwrite or replace any broken or damaged files causing the issue.

To reinstall Roblox, follow the steps below:

  1. Log out of your Roblox account.
  2. In the Windows search box, type in Programs and features, then click the Programs and Features icon from the search results.
  3. Scroll down until you find Roblox.
  4. Click Uninstall.
  5. Once the program has been removed, go to the Roblox website and log into your account.
  6. Click Download Now to get the installation file.
  7. Once downloaded, run the file to install the Roblox game on your computer.

    I’m on a Chromebook and I always get this problem. It has just really gotten annoying. I would get the problem every little bit and it wasn’t so bad. THEN I would get it about every 20 min. And it has gotten to the point where I can’t even play for more than 5 minutes without being disconnected and the error code popping up. Can you please help me?
