Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

MatrixYeeted, by your report your pc is just not getting a connection, not being an account configuration error.

Tell me what appears in this test please. Download the companion xbox console app > settings > network > NAT type

And connectivity

Let's try this IP and cache cleanup, please

Type CMD in the search bar;

Right-click on the Command Prompt option;

Click on the Run as Administrator option;

From the Command Prompt screen, execute the commands described below, pressing Enter at the end of each line:

ipconfig /release <Enter>

ipconfig /renew <Enter>

ipconfig /flushdns <Enter>

ipconfig /registerdns <Enter>

nbtstat -rr <Enter>

netsh int ip reset all <Enter>

netsh winsock reset <Enter>

These commands are for resetting IP configuration and network-related caches that may be stored on your computer.

1.On the desktop, press the Windows + R keys simultaneously to open Run;

2. At run type cleanmgr and click OK to open Disk Cleanup;

3. In the Disk Cleanup window, select the C: drive (if asked) and click OK;

4. In the Disk Cleanup for Windows 10 window, select the checkboxes for the files shown and click Cleanup System Files.

5. After cleaning, check the checkboxes that are not checked again and click OK>Delete Files.

Do you have antivirus, vpn or firewall?

If so, disable them and see if the error persists.

I remain at your disposal if you have any further questions.

If it still doesn't work, and only the login error message appears, then you will need to perform this configuration

So you just need to configure your internet devices now.

They are unconfigured, so have access restrictions, causing these errors.

If you do not have knowledge, I advise you to contact the ISP that they will do for you

set a fixed ip for the console/PC, open the ports described below, disable and enable the UPnP function and disable the modem firewall, if you have a modem and a router the process has to be done on both devices.

Put console/PC IP in DMZ zone.

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)

You can ask ISP(Internet Service Provider) for help
