Sometimes, a hard reset on your Xbox One console can solve most in-game problems. To do this, follow the steps below:

  1. Press and hold the Xbox button in the center of your controller to open the Power Center.
  2. Choose Restart Console.
  3. Select Restart to confirm.

To physically power cycle your Xbox console, follow these steps:

  1. Turn off your console by holding the Xbox button on the front of the console for approximately ten seconds. The console will automatically turn off.
  2. Unplug your console and press the power button a few times to drain all remaining power.
  3. To turn the Xbox console back on, plug the power cord back in and press the Xbox button on the console or your controller.

Fix #3: Check your Internet Connection

An inconsistent or slow internet connection will cause several errors upon logging in. It includes authentication errors such as the Roblox Error Code 901. Follow these fixes to solve internet-related issues on Roblox.

  • Reset your router or modem. Similar to the fix above, resetting your router will eliminate any glitches on your internet connection. You can also try power cycling your router by unplugging it and letting it sit for a few minutes before turning it back on.
  • Switch from a Wi-Fi to a wired (Ethernet) connection. Although Wi-Fi provides instant internet connection within its coverage, an Ethernet connection is more reliable and provides a stronger connection to your console or computer.
  • Change to another internet network. After trying the methods above, all you can do is try another network and confirm if you can log in properly to Roblox. Mobile network connections can also work but will incur charges on your mobile provider.
