i cant join or make a looking for group

Awesome! We are glad this is all sorted for you!

Take care and have fun ツ

Always happy to help!

Hello @bluejay#45!

Would you please try disconnecting your Xbox from the internet whether it be wired or wireless and power cycle your console. Sign back into your wifi and try again. If this does not fix the issue, we suggest preforming a Soft Factory Rest Xbox Support by selecting Reset and keep my games & apps. Also, you might need to check your NAT type. I would like you to check your NAT type if open because that could sometimes interfere. to check for the NAT type you can follow the steps below:

Settings > Network Settings > NAT type => It should be open.

If the NAT type is not open, you will need to open some ports with your internet provider. These ports must be open for Xbox Live to work: Port 88 (UDP) Port 3074 (UDP and TCP) Port 53 (UDP and TCP) Port 80 (TCP) Port 500 (UDP) Port 3544 (UDP) Port 4500 (UDP).

Did you do the soft factory reset?

I will look for a group only for fans of the song "Cake by the Ocean".

I wonder if I'll be successful in finding such group and if I do, I'll have to join.

You cant just pass up this opportunity and find out what they would play?

Hello Mcdowge2241,

I would suggest performing a factory reset while keeping your apps and games.

Before proceeding, make sure that you have access to your Microsoft account and Xbox Account.

Warning Resetting your console to its factory defaults erases all accounts, saved games, settings, and home Xbox associations. Anything not synchronized with the Xbox network will be lost. Your console syncs with the Xbox network automatically when it’s connected with the service, so if you've been offline for a while, connect to the Xbox service before taking these steps.

If you’re ready to reset your console to the factory default settings, follow these steps:

1. Press the Xbox button  to open the guide.
   
2. Select Profile & system > Settings > System > Console info.
   
3. Select Reset console.
   
4. On the Reset your console? screen, choose Reset and keep my games & apps
   

• Reset and keep my games & apps. Use this option as your primary choice when troubleshooting. It resets the OS and deletes all potentially corrupted data without deleting your games or apps. In some cases, if a corrupt game file is causing the issue you're troubleshooting, you may have to choose Reset and remove everything, but you should always start with Reset and keep my games & apps.
