If you receive an error message stating "Unable to Connect to Server. Please check your Internet Connection," it is likely due to your local network.

If restarting the console does not resolve the issue, you can try the troubleshooting steps below:


Check for Network or Service Outages

You can check for network or service outages by following the process below:

1. Check Xbox Live's status page.
2. Check all the physical devices on the network to ensure they are plugged in and powered on.
3. Perform a connection test on each device connected to the network.
4. Check the ESOTU Service Alerts page.

You can refer to this site about how to connect to Xbox Live.
