1] Check your network

First, we need to check the network connection and ensure that the bandwidth is not low. You can use one of the free Internet Speed Test services to check your bandwidth. If it is low, you should try switching to a different network, and rebooting your computer and router. If none of this worked, ask your ISP to resolve the issue.

2] Disconnect any VPN or Proxy Network

If you are connected to a VPN when configuring the Microsoft Store, your computer will get confused when trying to find your location. If the location doesn’t match your Microsoft Account, you will encounter an error such as 0x00000191. We recommend disconnecting from any VPN or Proxy Network to resolve the issue. After opening the Store, you can reconnect if required.
