NFS Unbound - Error codes 40010000 & FTJR2008 "Failed to create lobby”

Hi @Wolf_Tone4934 Can we try the following Xbox steps and check if this continues?

• Quit the game and other running apps from Quick Resume (For Series X|S consoles)
• Remove any connected device, or additional USB's from the console then restart the Xbox and check
• Check for updates 
• Try the steps in our Connection and Advance Connection Guides 
• Open you're Xbox NAT Type
• Change DNS settings (You can use the public google DNS primary: 8.8.8.8, secondary: 8.8.4.4, unless there is a different DNS you would rather use)  
• Persistent Storage 
• Go to settings > Select Device & Connections > Then Blue-Ray 
• Select Persistent Storage > Clear Persistent Storage 
• Alternate Mac: 
• Go to settings > Select General  > Then Network settings 
• Go to advanced settings > Alternate Mac address > Select clear 
• Select restart 

If this does continue we have a few similar threads with workaround you might be able to try as well. Here and Here. 

Cheers!
