The Problem Explained
There are various Roblox errors reported by the community throughout the many years of this platform’s existence. We cover all of those problems in our comprehensive Roblox error list, so if you’re curious to learn more, give it a quick look.
The 111 Roblox error is very common, and we believe the reason for that is that the problem it’s supposed to represent is very general.
When a user encounters the 111 error code on Roblox, they see a panel with the “Can’t join place. HTTP 400. Unknown Error.” message, which anyone would agree is quite vague and doesn’t speak much about the problem’s cause.
When it comes to solving this issue, it’s worth noting that most of the time there aren’t many things you can do, as it’s often triggered when the Roblox servers are down and not working properly.
However, there are some cases when this error is triggered due to a problem on the user’s end, such as a poor internet connection causing a timeout during a join attempt, corrupt game files, or an unsupported game version.
If you’ve already checked the current status of the Roblox servers, and there are no outages reported, it may be worth trying to find the issue on your end, in which case the methods listed in the sections below should help you out.
Fix 1: Ensure Your Connection Is Working Properly
If your internet connection is frequently dropping, or you’re experiencing a much higher ping than what’s allowed on the Roblox servers, it could be the reason you’re experiencing the 111 error code.
The best way to check this is by using Speedtest.
Next, we recommend flushing your DNS Resolver Cache, which can help with many network-related issues.
To do this, follow the steps below:
- Press Windows + S on your keyboard simultaneously. In the search field, type in Command Prompt, then right-click the first result and choose Run as Administrator from the list of options.
- In Command Prompt, type in ipconfig /flushdns and press Enter on your keyboard. You will get a returning message when the DNS Resolver Cache is successfully flushed.
Now that you flushed your DNS Resolver Cache, we recommend restarting your router and your PC. To do this, press the power button located on the backside of your router. The lights will go out and your internet connection will drop.
Now, restart your computer.
When your computer boots back up, power up your router by pressing the same button you used to switch it off.
Wait for a few seconds for the connection to restore, and then launch Roblox.
You should now be able to join the server you previously couldn’t due to the 111 Error Code if the problem was indeed related to your connection.
Fix 2: Clear Roblox Cache Files
Some users reported that clearing the Roblox cache files helped them fix the 111 error. This is likely due to the possibility of having corrupt cache files.
The easiest way to fix this is by clearing the cache files within the %temp% Roblox folder.
Here’s how to do that:
- Press Windows + X on your keyboard. Click on Run from the list of options.
- In the box that just opened, type in %temp%\Roblox and then press OK.
- Select all files from the Roblox data folder that just opened and delete them.
Note: You may need to confirm the action of deleting the Roblox files by pressing Yes on the Windows prompt screen.
Now you can launch the game again and see if the problem persists. Hopefully, the error will be solved, as this method helped many users.
Fix 3: Use A VPN
You can use a VPN to “mask” your connection and avoid a potential region-related connection issue that’s preventing you from joining a specific Roblox server.
This may not always work but it’s worth trying if you have no luck with any other method.
Keep in mind that if you’re not using a VPN designed for performance, your connection can become much slower due to the re-routing, and therefore you may experience high amounts of ping if you do manage to join the server.
If you aren’t sure which one to choose, we have a comprehensive guide covering many different VPN products that should help you make the right choice.
Fix 4: Reinstall Roblox
Last but not least, if all other methods fail, you may want to try fixing this issue by reinstalling Roblox. Since this requires more time compared to any other method listed above, we believe it should be a last resort solution.
However, do not disregard it, as reinstalling the game and overwriting the files with new, latest version ones, is often very helpful for solving such general issues like the Roblox 111 error.
Now you know more about the 111 Roblox error, one of the most frequently-encountered problems on the platform.
Since this is a general error code presented in numerous cases (even when the user is experiencing a different problem), there isn’t a direct solution for it, and so the fixes are quite general by nature too.
Hopefully, the methods listed in the guide above will help you solve this issue and get back to uninterrupted playing.
