This error can be frustrating as there are multiple causes for network errors. We have compiled a list of some easy yet very practical solutions for you that have worked for several other users and will most definitely work for you too.

What is Roblox Error Code 277?

Roblox Error Code 277 is a connection error, and like other network errors, it has a whole host of causes. Usually, it occurs when the server gets disconnected while playing the game, resulting in Roblox stopping the gameplay as it attempts to connect to a server.

An unstable or weak WIFI connection also leads to this error. Other causes include corrupted Windows files, the game being blocked in the Windows Defender Firewall, and missing game files. Outdated network drivers or a defective DNS range on your computer system could also be the potential causes of Roblox Error Code 277.

Regardless of whatever the cause may be, let’s explore the possible solutions you can try to resolve this issue.

Restart Your System

If you’re experiencing any issues playing Roblox, a simple solution is to restart your system. Many users have reported success with this method, so we suggest trying it before attempting anything else.

Test Your Connection

Once you’ve restarted your device, the next step is to test your network connection to ensure it’s functioning properly. Make sure the speed is over 20mbp/s by using this link to test it. If the connection seems to be stable, but you’re still facing the error, don’t worry. Let’s move on to the next step. 

Check Server Status

Oftentimes, players encounter the Roblox error code 277  even when their network is stable.  It is common for popular games like Roblox to experience server outages. In such cases, we suggest using the down detector to check for any reported outages for Roblox. Please note that server outages may occur only in specific regions. Therefore, it is important to select your country while using the down detector website.

Update Network Driver

Updating your network driver allows optimal gaming performance and ensures that your PC communicates properly and efficiently with the internet. Furthermore, it also helps eliminate any errors, bugs, or glitches. Here’s a step-by-step guide to updating your network drivers:

1. Press Windows Icon + X and select Device Manager.
2. Double-click on the Network Adapters section to expand.
3. The expansion will reveal a list of network adapters. Right-click on your network adapter and select the Update Driver. 

   

4. Select the “Search Automatically for Drivers” option to start a search in the Windows Driver Database.
5. Follow any additional steps required to complete the process.
6. Restart your PC to finish the driver installation.

Flush Your DNS Settings

Flushing the DNS settings has proven to be useful for quite a lot of users. Sometimes, your temporary network files cause network communication problems between different game modules. What flushing your DNS settings essentially does is that it removes the stored cache and force-retrieves information from the DNS. Here’s a step-by-step guide on how to do it:

1. Click on the Windows Icon and type Command Prompt.
2. Select Command Prompt from the search results.
3. Type in the command “ipconfig/flushdns” and press Enter.

   

4. Then, type the next command, “ipconfig/renew”, and press Enter to continue.

   

And that is the last step to finalize the process. After this step, relaunch the game to check if the problem is fixed.

Allow Roblox through Windows Defender Firewall

Including Roblox in the Firewall exceptions list is highly recommended to prevent false security threat flags. The Windows firewall is a crucial security feature that verifies server connections, but it can sometimes mistakenly flag Roblox as a security threat. Protect your system by taking action and ensuring Roblox is added to the exceptions list.

1. Press the Windows key and look up Windows Defender Firewall.
2. Then, click on the option that says “Allow an App or Feature through Windows Defender Firewall“. 

   

3. Next, click Change Settings. 
4. Now, Roblox might not be on the list of installed, so you will have to click on Allow another app. 
5. Look for the folder where Roblox is installed in your File Explorer.
6. Click Add.

And that should add Roblox to your computer’s Firewall exception list. 

Repair Corrupted System Files

If you encounter Roblox error code 277 while playing Roblox on your computer, it may be due to corrupt or damaged system configuration files. Just like we verify the installation files for games, this time around, you’ll have to do it for your PC files.

This can cause your computer to malfunction and result in poor performance. Fortunately, you can use your computer’s built-in utilities, such as System File Checker and Deployment Image Servicing and Management, to repair these corrupted files. Here are the steps to do it:

1. Open Command Prompt.
2. Enter the command “sfc /scannow” to run the System File Checker scan. 

   

3. After the scan is completed, either of the following messages will show up on your screen:
   Windows Resource Protection found corrupt files and successfully repaired them.
   OR
   Windows Resource Protection did not find any integrity violations.

We recommend you restart your system after the scan is complete to apply the changes you have made. If this fix does not work either, then fret not. Continue reading. We have a couple more fixes that will definitely fix the issue.

Remove ROBLOX Log Files

Oftentimes, temporary files can hinder your computer’s performance. Removing these files can improve functionality and free up space on your hard drive. As they are intended to be temporary, it is safe to delete them periodically. Follow the steps below to remove your Roblox log files:

1. Press the Windows key + R to open the Run Dialogue Box.
2. Enter the command %localappdata%\Roblox\logs. 

   

3. Then, select all the files which appear in the folder.
4. Next, right-click and select “Delete.”
5. Click Yes.
6. In the final step, restart Roblox and try connecting to the server again.

Close Background Application and Processes

Terminating any unwanted application or process running in the background ensures there’s no app or process clashing with your game software. This action ensures that Roblox has access to the best internet speed available. Here’s how you can close background processes via Task Manager:

1. You can open Task Manager by using the shortcut key combination “CTRL” + “SHIFT” + “Esc.” 
2. From the apps list, select the programs or processes you want to close.
3. Right-click on the running programs and select End Task.

   

4. Repeat the process to close other unwanted apps or processes of your choice.
