    DEV 401 Error trying too play MW2


    I can load the game and bring up the menus and it shows that i've connected to the XBOX Live but every time i try to load a game i get a DEV 401 ERROR message. Happens with multiplayer, Warzone, DMZ...every time i select start match i get a pop up and get booted.

    I Googled and found info on fixing it by changing my "FPS" setting to unlimited...but i can't find the option ( PC Only? )

    :)

    Hi and thanks for reaching Microsoft Xbox gamer's community.
    My name is Josef.
    I'm an Independent Advisor

    Hope you're doing great today despite this Weimer369

    I can suggest you some things to try, but if the issue persist you may need to reach Activision support

    https://support.activision.com/options

    A. Power cycle the Xbox:
    1. Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.
    2. Unplug the console's power cable from the console and from the power outlet. Wait 5 minutes.
    Important: Be sure to wait at least 5 minutes. This step resets the power supply.
    3. Plug the console power cable back in.
    4. Press the Xbox button on your console to turn it on.

    After that, remove and re-add your profile on the console.
    In case you need it, here's how to remove and re-add:
    https://support.xbox.com/help/account-profile/m...

    Also disconnect your router from power for about 3 minutes. Then connect it again an when everything is working, enable all the remote play features and try again

    B. Try using a custom DNS address:
    go to Settings > Network > Advanced Settings

    Once you’re inside the Advanced Settings menu, go to DNS settings and select Manual from the list of available options.
    When you get to the next screen, enter 8.8.8.8 in the box associated with the Primary DNS and 8.8.4.4 in the Secondary DNS box.

    Once the default DNS addresses have been changed, restart your console and see if the issue has been resolved at the next console startup.
    If that doesn't work use 1.1.1.1 as primary and 1.0.0.1 as secondary

    C. Clear your MAC address
    Go to Settings > Network > Advanced Settings > Alternate MAC Address
    Select Clear, restart your console and give it a new try

    D. Try connecting your console to a completely different Wi-Fi network
    For this purpose you can share mobile data via Wi-Fi hotspot

    E. Reinstall the game

    F. Do a factory reset for your console but keeping games and apps
    Go to Settings > System > Console info > reset and then select keep my games and apps
    **Make sure to know the email and password for all your accounts

    Game Pass friends & family share

    I'm experiencing the same issue with the invites I send.



    When the invited person (all in my region) clicks the invite email or follows the invite like it doesn't work, they get a spinner with "Working".

    If I open the dev console the "checkInvitation" request is an error (401).



    I think this is a bug.

    I have been trying to report this to Microsoft, but I cannot seem to get a callback or chat to a support agent.
