VPNs can sometimes be incompatible with Roblox. While VPNs are great at keeping you safe online, they can cause issues when you're trying to play online games. Try disabling your VPN and then open Roblox again to see if the issue is fixed. On the flip side, if you're not using a VPN, sometimes adding a VPN can fix error code 0.
- If you're using a VPN set up on your Windows computer, go to Settings > Network & internet > VPN , then toggle your VPN .
- If you're using a VPN set up on your Mac computer, go to the Apple menu > System Settings > VPN , then toggle your VPN off. ^{[1]

Restart Your Router

- On Android or iOS, go to the Google Play Store/App Store and look for the Roblox app, then tap Update .

Delete the Roblox Cache

There may be corrupt files in your Roblox cache. A cache is a group of temporary files that allow websites and applications to work faster, but sometimes these files can become corrupt, which leads to errors. Clearing the Roblox cache will not delete your Roblox progress, as that is stored in Roblox's servers. Here's how to delete the cache:
- Windows: Open your File Explorer and type %localappdata% in the path bar near the top of the window. Open the Roblox folder and delete everything inside. Restart your computer and check to see if you still get error 0.
- Mac: Open Finder, go to Go > Go to Folder… , then type ~/Library/Caches/ . Click the Go button and open the Roblox folder. Delete everything inside the folder, then restart your Mac to see if you still get error 0.
- Android: On Android, the location of the cache may vary depending on your phone's model, but look in your Settings for a Storage option, then select Apps . Scroll until you find Roblox, tap on it, and select Clear Cache .
- iPhone & iPad: On iOS, the best way to clear the cache is to uninstall the Roblox app and then reinstall it so only the essential files will be installed.

Check for Server Issues

Just like any other online game, Roblox can sometimes encounter server issues, which can cause errors when playing. Go to Roblox's server status page and check to see if there are any issues. If there is, they will be reflected on the page. Unfortunately, the only thing to do if there are Roblox server issues is to wait for them to be fixed.

Reinstall Roblox

If nothing else works, try a fresh Roblox installation. While this is a somewhat drastic measure, it will entirely reset your Roblox software in case there was some other glitch or bug that was occurring. Uninstalling Roblox will not delete your Roblox progress, as that is stored in Roblox's servers.
- Windows: Right-click the Start button and select Apps and Features . Scroll until you find Roblox, then click the Uninstall button. Then, go to Roblox's website and download a new copy of Roblox to install .
- Mac: Open Finder and go to your Applications folder. Select the Roblox app and drag it into the trash, which may prompt your Mac to ask for your username and password. Once the app is in the trash, empty the trash can by going to Finder > Empty Trash . Then, go to Roblox's website and download a new copy of Roblox to install.
- Android: Open the Google Play Store and tap your profile at the top right. Select Manage apps & devices > Manage , then tap the Roblox app. Tap Uninstall , then go back to the Google Play Store and reinstall Roblox.
- iPhone & iPad: Press and hold the Roblox app until it begins to shake. In the context menu, select Remove App . Then, open the App Store and reinstall Roblox.
