What is the Roblox Error Code 277?
The Roblox Error code 277 is generated when a runtime error in one of scripts on the game server has occurred. A runtime error means that an issue with the game logic or scripts was running incorrectly and it interfered with how the client interpreted that data which resulted in one or more errors occurring on-screen. In most cases, these error code will be generated automatically by the client as soon as they are detected and no additional intervention should be required for them to be fixed. However, there are some cases where they do not get resolved automatically and this could result from outages of parts of the network infrastructure like DNS services.
Why does the Roblox Error Code 277 Occur?
The Roblox Error code 277 is one of the most frustrating Roblox error codes you’ll ever face in your gaming experience. It’s so common and has happened to me a lot of times, but there are many reasons for this error – some more embarrassing than others! The most common reasons are the following:
- Poor Internet Connection
- Disconnected/Lost Connection
- Connection Error
- Roblox Game Server Issues
- Software Glitches and Bugs
- Corrupted Windows System Files / Windows Registry files

Fixing the Roblox Error Code 277
Method 01: Updating the Default Browser to the Latest Version
Updating your internet browser (Internet Explorer, Mozilla Firefox, Google Chrome) is an easy way to ensure that you’re getting the best Roblox experience. You need a reliable and up-to-date version of whichever browser you use in order for it to work properly with all game components. With outdated browsers, there’s no guarantee that everything will be working as planned, and there is a chance that it would cause the Roblox Error Code 277 – so if this problem arises then just update!
Method 02: Launch Roblox in Compatibility Mode
Windows 10 is the latest Windows operating system version released by Microsoft, but many older apps might not run well on this Windows version. This may be because Windows 10 still needs to iron out some bugs and glitches before they can work together with all of their new features. If you encounter error code 277 when running Roblox, try changing the Roblox compatibility mode settings so that the game will load in compatibility mode instead!
Step 1: Locate the Roblox installation folder and locate the executable (.exe file)
Step 2: Right click on the Roblox exe file (RobloxPlayerLauncher.exe) then select Properties
Step 3: Navigate to the Compatibility tab then put a check on the “Run this program in compatibility mode for”.

Step 4: Press Ok then try to run Roblox app
Method 03: Launch Program Compatibility Troubleshooter
Just like Method 02, the Program Compatibility Troubleshooter is another way of running the game in Compatibility mode to fix compatibility problems.
Step 1: Locate the Roblox installation file folder and locate the executable (.exe file)
Step 2: Right click on the Roblox exe file (RobloxPlayerLauncher.exe) then select Properties
Step 3: Go to the Compatibility tab then press the button “Run compatibility troubleshooter”

Step 5: Once the recommended settings are shown, select the option “Try recommended settings”

Step 6: Wait for a few seconds while another dialog box appear then select “Test the program”

Method 04: Delete Roblox Logs
The Roblox app, just like other apps produces temporary files called caches. This cache file contains user settings and history of games played as well as other game logs custom settings. The purpose of these cache is to load your game faster while also maintaining the user’s input when they return for another round in their favorite Roblox world. However, even with all that good stuff going on you may experience Roblox errors caused by corrupted data or simply running out of space because it takes up a large chunk from resources; which can lead to error code 277 popping up occasionally if not fixed quickly enough!
Step 1: Enter %localappdata%\Roblox\logs in the Windows search box then press Enter
Step 2: Select all the files by pressing Ctrl + A then press the Delete key to delete all files
Step 3: Again, in the Windows search bar, type this text %USERPROFILE%\AppData\LocalLow\RbxLogs\
Step 4: Again, delete all the Roblox log files by pressing Ctrl + A, then press the Delete key
Method 05: Connecting to a Different Network
Roblox error code 277 can be related to your router’s ports. Some users reported that the glitch happened when they were connected to a network, like their home WiFi but disappeared when using data from mobile service providers. If you’re playing Roblox on a wireless connection at work or in your house and have encountered this issue with it before, try switching over to different network if available; speed should not drop below 4 MB/s for optimum performance.
Just take note that high-speed internet is not easy to get in some areas. So, if you can’t connect an ethernet cable to the computer and want a hotspot for WiFi, make one via your 4G or 5G mobile data. Roblox also has their own mobile app so that might be another alternative!
