Disconnecting from xbox 360 live while playing in xbox series x

Hi there! This is Ronnie, an independent advisor.

Nice to meet you and I hope you are having a great day!

I understand you need help with your Xbox 360 issue.

Please try this:

Please Go to Settings:

> Network

> Network Settings

> Advanced Settings.

Select the alternate MAC address and then select delete/clear.

You must restart the console for the change to take effect.

And please do this:

Set DNS manually. To manually configure DNS settings, follow the steps below:

1.- Go to Settings

2.- Select Network

3.- Select Network Settings

4.- Select Advanced network settings.

5.- Go to DNS Servers, set it to Manual> enter 8.8.8.8 in the 'Primary' field and 8.8.4.4 in 'Secondary'

If that does not help, try using a different network instead like using your mobile hotspot just to isolate more of the issue.

Xbox series X will be the next console of the Xbox franchise. Like the jump from Xbox 360 to Xbox one. You will be able to play you're Xbox one games on the Series X and the games coming out will be out on Xbox One as Xbox series X for a limited time.
After a while they will quit making games for Xbox one and focus on Xbox Siries X

When I want to disconnect the electricity from the device, I turn off the device completely through the settings

You should not disconnect the power from the Xbox Series X while it is in sleep or shutdown mode even if the fan does not rotate ???

Elaborating slightly: None of our family accounts on the same xbox aside from mine have xbox live gold (ultimate in my case). Previously on xbox one x, for instance, my wifes xbox account, she would sign into MWF3 360, go to live and join games. Now on
xbox series X, same exact steps, it throws the error. You could always play under other accounts as long as one account was a live paid account (360 or regular xbox one x titles), now it only works for one x or one x series x titles.

Yes, if you purchase the game from the Xbox 360 marketplace, you can play it on the Xbox 360, Xbox One or Xbox Series X|S.

As for what Hardcore Games said, you can still buy Xbox games for the Xbox 360, and play them on the Xbox 360, and if they are backward compatible, play them on the Xbox One & Xbox Series X|S.
