error code Additional Authentication needed related to connectivity issues with Xbox console

Hi, my name is Fernando and I am an independent consultant for Microsoft products.

First redefine your console:

"https://support.xbox.com/en-US/help/hardware-ne...;

Choosing the option "Reset and keep my games & apps" it'll keep your apps, games and saves.

After that contact your ISP and ask them to open the following ports in your router:

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)

Try to use a wired connection, it's always the better option to play online or download content..

Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

Hello, how are you? My name is Mateus. I'm an Independent Advisor and I'll be glad to help you today.

First I'm sorry you're having this problem.

Please try the solution below if you are still having problems with authentication.

If you are running into the "Additional authentication needed" error message or running into the error code 0x4000000000000000

while trying to connect to your network, give the following steps to try:

From the error message, select Enter alternate MAC address at the bottom of the screen, then select Manual

On a wireless PC connect to the Wi-Fi network you are trying to connect your console to. Once you have connected to your wireless network, you will now need to get the MAC address (physical address) of the PC

From your PC, open Command Prompt by typing CMD in the Cortana search box and then type ipconfig/all

Your MAC address is listed as "Physical Address" and is shown under the Ethernet adapter Ethernet section. Copy this number down and go back to your Xbox One console.

From your Xbox One console, enter the MAC address of your PC into the Alternate Wireless MAC address field. Once you have entered your MAC address, try connecting to your wireless network again.
