    Hello,

    Welcome to the Microsoft 365 & Office Community.

    Good day. Here are some steps you can try:

    1. Press Win + R, type winword /safe, and press Enter. This will launch Word in Safe Mode.

    2. If it opens normally, go to File -> Options -> Add-ins and temporarily disable the add-ins to identify any potential conflicts.

    3. If the error persists, press Win + R, paste the command appwiz.cpl, locate and select Microsoft 365/Office, click Change, and then select Online Repair.

    Please let us know the outcome.

    This error can be caused by the Office sign-in flow on Windows 11 Home, even when internet access is working normally.

    Try these steps in order:

    1. When Word asks whether to sign in to all apps and websites on the device, select No, sign in to this app only.
      • This avoids device registration, which can trigger error 2604.
    2. Check the work or school account connection in Windows.
      • In Windows Search, open Access work or school.
      • If the correct account is missing, select Connect and add it.
      • If the wrong account is listed, select it, choose Disconnect, then select Connect and add the correct account again.
    3. Clear stored Office credentials.
      • Open Control Panel > User Accounts > Credential Manager.
      • Under Windows Credentials and Generic Credentials, remove entries related to Microsoft 365 or Office.
      • Restart the PC, then open Word and try signing in again.
    4. If multiple Office or work/school accounts were previously added, remove extras.
      • Go to Settings > Accounts > Email & accounts.
      • Remove extra work or school accounts.
      • Then restart and sign in again with the intended account.
    5. Verify the network connection status in Windows.
      • Go to Start > Settings > Network & internet.
      • Confirm the connection status shown at the top.

    If the problem happens only on a wired connection and not on Wi‑Fi, update the network card driver first. If that does not help, disable IPv4 Checksum Offload:

    • Open Control Panel > View network connections.
    • Right-click the network adapter > Properties > Configure > Advanced.
    • Select IPv4 Checksum Offload and set it to Disable.
    • Select OK.
