Xbox Cloud Gaming sign-in error – ERR_CONNECTION_REFUSED

I’m trying to play Fortnite and other games using Xbox Cloud Gaming on my MacBook, but none of the games will launch.

Whenever I press Play, I get a “Something went wrong” error.

I’ve discovered that Xbox sign-in is also failing. When I try to sign in, it redirects me to:

play.xbox.com/auth/msa/error

I’ve also tried opening sisu.xboxlive.com, but Chrome displays ERR_CONNECTION_REFUSED.

Things I’ve tried:

• Chrome and Safari
• Chrome Incognito mode
• Clearing Xbox website cookies
• Turning my VPN on and off
• Disabling iCloud Private Relay
• Checking that no proxy settings are enabled
• Disabling browser extensions

I can sign into my Microsoft account normally, but Xbox doesn’t seem to recognise or complete my sign-in.

The error reference shown on the Xbox page is: OiPs/tytElfXR/UCWbnat/.1.5.0

Could someone help me identify why Xbox authentication isn’t working and how to fix it?
