Can't install games or apps on Xbox or pc - networking issue?

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today Sluda
Letts try isolating the issue first

Please open xbox console companion app >Settings > Network and tell me what's saying on NAT type

In the meantime try this:

Right-click the Windows Start button in the lower-left corner of the main screen, and then select Windows PowerShell (Admin).
In the Administrator: Windows PowerShell screen, type the following command and press Enter:
Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers

In the same window, type the following commands and press Enter:
Remove-Item -Path "HKLM:\System\CurrentControlSet\Services\GamingServices" -recurse

Remove-Item -Path "HKLM:\System\CurrentControlSet\Services\GamingServicesNet" -recurse

Restart your device.
Start the Xbox application. You should see a blue banner with the following message: "This app needs an extra component. Gaming Services is needed for playing some games. Administrator approval required. Install"
Select Install to reinstall Gaming Services.
After the installation is complete, you should be able to install and start games again.

I'll be waiting for your reply

did u ever figure out how to fix this, or did anyone? I have the same issue with the Game Pass app on Android, it can't detect my Xbox One that's on the same network, I can't do any remote installations & therefore can't complete the Xbox Pass quest for
doing a mobile installation...

I've the same problem and have tried the same things as you've listed. Both my X and original Xbox are stuck with this error. Apps will install, but no games will.

However, if I change from my Huwaei 4g router (three network) router and use my adsl line router/network, it all installs. Albeit slowly (being the reason I got the 4g as well)

Xbox Beta pc stuff downloads without issue on either network. So I can't even say it's three blocking large downloads from MS.

It's extremely frustrating.

Hello There ! I highly recommend following the steps mentioned on the links bellow to resolve the issue :

Thanks again.

Somewhat reluctant to change the router settings, I decided to dig out my old laptop, installed the Xbox app and tetris app onto it. It worked. Good news as it shows it must be a config issue on the PC itself - the laptop was tested on the same network.

Any other suggestions on modifying settings on the PC itself to get the game working?
