The Problem Explained

As mentioned in our complete Roblox Error List guide, the 277 error is probably caused by your IP address altering while already connected to a Roblox server, which could occur when your router restarts due to a power outage or a planned IP reset issued by your Internet Service Provider.

The Roblox 277 error can also appear due to other issues with your connection, such as having a high amount of ping while playing.

In other, more rare scenarios, the error could appear due to the server crashing and going offline.

Roblox Error Code 277

One of the most confusing things about the 277 Roblox error is the fact that users who experience it often see an error screen with a different code, as reported in this post on the official Roblox forum.

It is indeed true that connection issues can lead to multiple different error codes while playing Roblox, but all of them can be solved with different fixes. Once again, we cover the reasons and solutions for all Roblox errors in our comprehensive guide.

For now, we’ll focus on solving the 277 Roblox error, but note that by applying the fixes mentioned below, you could potentially solve other error codes as well, as most of them in this group are caused by an issue with your connection.

Fix 1: Delete The Roblox Logs Folder

Delete or Remove

One of the main fixes for this problem is removing the folder where the game stores log files. According to some users, these log files can often confuse the game into thinking there are issues with your connection, and deleting them gets rid of the 277 error.

To do this, follow the steps below:

  1. Press Windows + R on your keyboard at the same time to open the Run command window.
  2. Type in “%localappdata%Robloxlogs” and press Enter on your keyboard to initiate the search.
  3. Inside the folder that just opened on your screen, press Ctrl + A to select all the files, and then remove them by pressing the Delete button on your keyboard.
  4. Open the run command window again, but this time type in “%USERPROFILE%AppDataLocalLowRbxLogs” and press Enter on your keyboard again.
  5. Within the folder that opened, delete all the files just like you did in step 3.

After removing all Roblox logs, you shouldn’t have trouble playing the game anymore. But if the issue still persists, you can try the solutions for your connection listed below, which address the frequent reason behind the 277 error.

Fix 2: Clear Your DNS Cache And Restart Your Router


Clearing your DNS Cache is beneficial for your system if you haven’t done it in a while and also helps with many various errors for multiple online games, one of them being Roblox. Luckily, it also seems to help with the Roblox 277 error, as reported by other users.

Here’s what you need to do to flush the DNS cache on your computer:

  1. Press Windows + S on your keyboard simultaneously, and within the search field that opened, type in Command Prompt, right-click the first result, then choose Run as Administrator, as shown in the image below.
    right clicking Windows 10 Command Prompt and selecting Run as Administrator
  2. Within the Command Prompt Window, type in: “ipconfig /flushdns” and then press Enter on your keyboard to initialize the command. You will get a returning message confirming that you successfully flushed the DNS Resolver Cache, as shown in the image below.
    ipconfig /flushdns, Successfully flushed the DNS Resolver Cache

Although it’s not mandatory, we recommend restarting your router after flushing your DNS Cache. You can do this by switching the device off using its power button, then waiting for five minutes and turning it back on again. While you’re doing this, you can also restart your PC.

Once your PC reboots and your connection to the internet is restored, re-launch Roblox and try to join the server you previously couldn’t or were getting disconnected from. You should now be able to play without experiencing the Roblox 277 error any further.

Fix 3: Add Roblox To Your List Of Firewall And Antivirus Exceptions


Sometimes our firewalls and antivirus programs block our connection to specific services and game servers as they mistake these connections for something potentially harmful. Although it’s all for a good cause, these mistakes can often prevent us from launching a perfectly safe app or playing a game, such as Roblox.

Several users have reported that adding Roblox as an exemption in their firewall preferences (and antivirus software too) assisted them in resolving the issue.

To do this, simply follow the steps below:

  1. Press Windows + S on your keyboard at the same time to open the Windows search panel. Then, type in Firewall & Network Protection and press Enter to initiate the search command.
  2. Scroll down within the panel until you see the “Allow an App Through the Firewall” option, and then click on it, as shown in the image below.
    Windows Allow an app through the firewall
  3. Search for the Roblox executable file on your system, and then add it as an exception in your firewall.

This will make sure your connection to any Roblox server won’t be stopped by the Windows security settings, and if that was causing the issue, you should no longer face it while playing.

You can do the same with your antivirus settings, but since everyone is using a different antivirus, you’ll have to manually search the guide for adding exceptions.


That’s all you need to know about the Roblox 277 error, which sometimes occurs due to an issue with the server but, most of the time, it’s a problem on the user’s end and related to their internet connection.

Luckily, all the methods listed above were proven helpful to multiple users, and when applied correctly, they should help you overcome the issue as well.
