If you are using a PC/Mac or mobile device for playing Roblox games, restart your device to give it a fresh start.

Also, restart the Router/modem as it will remove clogged caches and give it a fresh start.

The router or the modem could be restarted by simply removing the power cable from the wall socket and plugging it again.

2- Clear Roblox Cache & data

When the Roblox game is installed on your device, it creates a folder for app data and cache file storage.

If the cache or data files go corrupt due to any reason, it creates problems for the app client (Roblox) to communicate with the Roblox server and hence a popup window appears on the screen with error detail.

Deleting the app data from this folder (fresh app data will be collected again as you play the game) will remove the file causing this problem and probably fix the error.

Don’t worry, it will not affect the performance of the Roblox game app.
