Fortnite is showing nothing but a navy blue screen when trying to access it through Xbox...

The most I can say is to try again. It eventually will start working after a little while. I haven't had this problem at all since the Season 4 update.

hi im having the same problem on my phone, i tried using different browser and restarted my device but it still wont work.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.

Hope you're doing great today despite this Legoloco7

May I know if you tried using a completely different web browser?
Or try using the cloud gaming feature via private / incognito mode?

Or if possible, try using a different device and test there if the issue persists

Hi, don't worry!

There are no dumb questions, if you don't mind. Please try checking if maybe there are some pending updates for your other PC (the one with the problem)

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click the Download and Install Now option, if available (Install optional updates as well)

Also, check the Microsoft Store for any updates on the Xbox apps and its services and update everything too.

If the issue persists try factory resetting Edge or Brave (or if you don't mind. Reinstall the browsers)

If that doesn't work and in case you have a VPN, firewall, DNS service or similar enabled. Disable each one and give it a new try

--------

If finally the issue persists, please share feedback with the xbox team

To do this click your profile picture > scroll down to the bottom > give feedback > give details, if possible attach the screenshot and your OS, etc (all this is useful info, that helps to the team to diagnose more easily the problem)

I tried with Edge rather than Brave and got the same issue, so yeah, that didn't work. I just tried it on my other computer, and now it's working fine. Thanks, I think. I feel like I shouldn't have submitted this question now.
