"Sorry, looks like our service isn't working right"

I recommend that you turn off all the systems that use the internet and then reset your router once the router is restarted and that this one starts up again the computers that use internet one by one, including your xbox

Restarting router and network settings did nothing. Completely unplugged Xbox and network cable, all good to go

I would suggest running a network test in your Xbox One settings menu and checking the results of the test. If you find that anything stands out this interactive guide may be of help:

Hi there,

I'm sorry to hear this is happening. Now just for clarification are you on the Xbox 360 or Xbox one? If you're on the Xbox One I suggest for you to clear the console's network cache (MAC address).

To clear the alternate MAC address(Network cache)on the Xbox One console follow these steps:

• Go toSettings
  
• Select Network > Network Settings
  
• Select the Advanced Settings
  
• Next choose the Alternate MAC Address
  
• Select clear and restart
  

Hope to hear back soon, let us know if this helps.
