How to fix Roblox error code 400

There are multiple methods of solving this issue, so we’re gonna list all of them and you can rule out each one depending on if it fixes the problem or not. There is no sure way to know which method will work, as there can be many reasons for the error appearing in general. Here they are:

  1. Remove temporary files
  2. Resetting your Internet
  3. Reinstall Roblox
  4. Manage your Firewall
  5. Solution for mobile devices

Remove temporary files

This solution tackles the issue of your browser. Sometimes, temporary browser files may cause conflicts between the game and your browser, causing error code 400. To perform this check, open your default browser, and from here, go to Settings and temporary files and cache. This method will make sure that your browser is clean before trying to connect to Roblox again.

Resetting your Internet

When all else fails, the turn off/on method is usually the way to go. This method will have you tweak some of your Internet options in order to get a smoother connection going. The jist of it is to reset your browser completely, so here’s how to do that:

  1. Go to Control Panel
  2. Go to Internet Options
  3. Advanced
  4. Find the Reset button and click it
  5. Restart your PC

Starting the game back up after restarting your PC should resolve the error. If not though, you can continue on to the next solution.

Reinstalling Roblox

One of the reasons your game might be showing this error code is a poor game installation or corrupted game files, so for this next solution, we’re going to be deleting Roblox completely and reinstalling it from the ground up. In most cases, any error should be resolved by reinstalling the game, including this one.

Manage your Firewall

As we’ve mentioned before, error code 400 can also have something to do with the server you’re trying to connect to, so checking up on your Firewall can help the issue tremendously. Open your Firewall and make sure that Roblox isn’t blacklisted or restricted by it. Likewise, you can also check your antivirus for any suspicious blocking. Antivirus software might sometimes register the game you’re playing as an attempt at malware, so it blocks it.

That would be everything when it comes to the PC solutions for error code 400. If you’re encountering the issue on a mobile device, simply go into your settings and clear the app cache. That should solve the error. When it comes to your PC, however, one of these solutions should have worked to fix your problem.
