Microsoft’s Xbox is well known as one of the top gaming consoles on the market. Numerous games, including Xbox exclusives, can be used on the Xbox consoles. That combined with affordable prices and high end hardware has made the Microsoft gaming console rivaled only by a few.

Because of its popularity, Microsoft has added an application on Windows 10 that allows PC users to access all of Xbox’s features. However, users may face an issue where the Xbox app server blocked connectivity on Windows 10. If you are facing this same problem, then the instructions in this article will help you resolve the issue. Below you will find information on not only how to resolve the connectivity problem, but also info on major causes of this error. 

Causes of the Xbox app server blocked connectivity on Windows 10

There are multiple reasons why your Xbox application is blocked on your Windows OS. Identifying the issue is the first step in the process of fixing the error. Here are the major causes of the connectivity issue:

1.Incorrect network adapter

You could be having connection issues because your Xbox application is connecting to the incorrect network. Perhaps, your computer is connected to the internet through Wi-Fi as well as Ethernet. If this is the case, then the application may constantly switch from network to network, causing complications.

Furthermore, Wi-Fi connections are generally less stable than Ethernet connections. Therefore, you will want to ensure that you are connected through an Ethernet cable before you start your Xbox app. Also, you may want to turn off your Wi-Fi when you are playing online Xbox games.

2. Antivirus blocking Xbox app’s connection

If you are using an antivirus program other than Windows Defender, then you will want to ensure that its settings are properly configured. Typically, antivirus programs will block applications for security reasons, even if the application is completely trustworthy. Thus, you will want to check out the app settings of your firewall program to see whether or not the Xbox application is blocked.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
