    Try switching accounts from the top of your Dashboard. Enter in your email address and password associated with your Central account, and see if that refreshes and synchronizes your account with your app.

    Otherwise, @Alexandru_BD or @Mike_BD would you check into this, please :)

    Kind regards,

  • Hello @NISHITH,

    You still have a valid Total Security subscription in your Central account that will expire in 2025. Try to refresh Bitdefender and link it again to the Central account by following @Scott's steps above.

    If you are getting the message "Unable to connect to the server" when signing in to Central from the product, first restart the computer then try again to sign in. If the message persists afterwards, please check for any other security solutions and uninstall them. Then restart your computer and try again to sign in.

    If the issue persists, do the following:

    Open a Command prompt window with Admin rights - In the command prompt window, run the following commands:

    a. ipconfig /flushdns

    b. netsh winsock reset all

    c. netsh int ip reset all

    Restart the PC and try again.

    Proceed to DNS settings if the message persists:

    Change DNS server settings: - Go to Control Panel. - Click on Network and Internet. - Click on Network and Sharing Center. - Click on Change Adapter Settings. - Double-click your active adapter (network) and choose Properties. - Select Internet Protocol Version 4 (TCP/IPv4), then click Properties. - Select Use The Following DNS Server Addresses and enter the following addresses: - Preffered DNS server: - Alternate DNS serve: - Click OK to confirm, then restart the PC.

    NOTE: The steps work for Windows 8 & 10 as well. Try again to log in to Central from your product.
