NETWORK CONNECTION PROBLEM

please yesterday I wrote here that I have a problem with the network connection in the game nhl 25 when I turn it on it says there is a NETWORK CONNECTION PROBLEM and I did these steps 

1) I reset the xbox 

2) I restarted the router 

3) I erased the mac 

4) I reinstalled the game 

5) I unplugged the power cable 

6) I restarted the xbox 

so what else should I do so that it doesn't start because I don't know anymore and I don't like doing those steps over and over again if you can fix it I will be grateful and please fix this error for me

thank you very much for understanding
