Possible Solutions to the Roblox Error Code 273

We understand that encountering this error can be frustrating and hurt your overall gaming experience. To help you get back into the game, we recommend trying the following solutions:

Verify Internet Connection and Reboot Router

One of the simplest solutions to fix Roblox Error Code 273 is to verify if your internet connection is stable and functioning properly, as an unstable internet connection is often the cause of such errors. You should also reboot your router as doing that will reset your connection with your internet service provider (ISP) and maximize the internet performance for the devices on the network. Here’s how you can do that:

1. Unplug the power and Ethernet cables from the modem.
2. Wait 1-2 minutes for the modem to fully power off.
3. Reconnect the power and Ethernet cables to the modem.
4. Wait for the internet light to turn on.

Once your router is rebooted, launch Roblox again and check if the error is resolved.

Note: Consider using a wired connection for better connection and reliability.

Change Login Credentials

Changing your Roblox account login credentials, which include your password and Two-factor authentication (2FA), can help resolve any potential authentication issues that might be causing the error. It also helps safeguard your account if it has been breached by any unauthorized individuals. Follow these steps to change your login credentials:

1. Go to Roblox’s official website.
2. Log in to your Roblox account.

3. 

   Find the Gear icon on the upper-right corner of the website and click on it.

5. Click on Account Info > Change Password.

   

6. Change your password and confirm the changes to save them.

If your issue was caused by an account breach, this should help resolve it.

Sign Out of All Devices

To ensure that only one device is accessing your Roblox account at a time, it is recommended to force a log-out on all devices. This prevents conflicts and eliminates the possibility of multiple sign-in sessions triggering the error. Here’s how you can do that:

1. Go to Roblox’s official website.
2. Log in to your Roblox account.

   

3. Find the Gear icon on the upper-right corner of the website and click on it.
4. A pop-up menu will appear, choose Settings from the list of options.

   

5. Click on Security > Log Out of All Other Sessions.
6. A dialogue box will appear asking for confirmation, click on Log Out to confirm your decision.

Disable Antivirus Software

Occasionally, overly protective antivirus software can block Roblox and result in Roblox Error Code 273. Temporarily disable any antivirus program you have running to check if that resolves the problem. Remember to re-enable it after troubleshooting. Here’s how you can do that:

1. Identify and open your antivirus
2. Find the ‘disable/turn off’ option and click on it.
3. Confirm the changes and verify that the software is disabled.
4. Run Roblox and check if the fix worked.

Change Firewall Settings

Another reason for the error could be your firewall settings blocking Roblox’s game client from connecting to the servers properly. Here’s how you can fix that:

1. Go to your computer’s Settings.
2. Search for ‘Firewall & network protection’ and click on it.
3. Click on ‘Allow an app through firewall’ at the bottom of the screen.

   

4. Next, click on ‘Change settings’ to edit the settings.

   

5. Find Roblox and tick the box on the left to allow the app.
6. After that, tick the boxes for both ‘Private’ and ‘Public’ on the right side of the screen.

   

7. Press ‘OK’ to confirm changes.

Doing this should help resolve your error Roblox if your error was being caused by Firewall settings by bypassing network restrictions in Roblox.

Clear Browser Cache

Clearing your browser’s cache can eliminate any temporary files and data that might be causing conflicts when accessing Roblox. This solution is particularly relevant if you are playing Roblox through a web browser. Follow these steps to clear your browser cache:

1. Navigate to your browser’s Settings.

   

2. Find Privacy and security from the menu.
3. Click on Clear Browsing Data and confirm changes.

6. Type ipconfig /renew and press Enter.
7. Type netsh winsock reset and press Enter.
8. Once you’re done inputting all the commands, reboot your PC and check if the fix worked.

   

Port Forwarding

Another possible cause of the error could be the improper configuration of your network settings, which can disrupt the connection between your game client and the Roblox servers. In such cases, configuring your router’s NAT settings correctly can help. Follow these steps below to manually set up port forwarding (NAT):

1. Open your internet browser and open your router’s settings. This can be done by entering your router’s login URL or default IP address (Usually found on the back/bottom of your router)
2. Log in by entering your account details.
3. Navigate to Settings > Advanced > Port Forwarding.
4. Switch on these ports manually:

• TCP: 3074
• UDP: 88, 500, 3074, 3544, 4500

5. Save the changes and restart your router.

By following these steps and configuring your router’s NAT settings correctly, you can potentially resolve the error and establish a stable connection between your game client and the Roblox servers.

Preventing the Roblox Error Code 273

Encountering the Roblox Error Code 273 can be frustrating so here are some tips to help you avoid this error in the future:

• Regularly update your password and enable Two-factor authentication (2FA) for added security. By maintaining strong account security measures, you can reduce the risk of account breaches and unauthorized access to your game.
