    Enable TLS 1.2 in Internet Explorer

    QuickBooks uses Internet Explorer settings for secure connections. Enable TLS 1.2:

    1. Press Windows key + R
    2. Type inetcpl.cpl and press Enter
    3. Click the "Advanced" tab
    4. Scroll down to the "Security" section
    5. Uncheck "Use SSL 3.0"
    6. Uncheck "Use TLS 1.0"
    7. Uncheck "Use TLS 1.1"
    8. Check "Use TLS 1.2"
    9. Click "Apply" then "OK"
    10. Restart your computer

    Important: TLS 1.2 is required for secure connections to Intuit servers. Older protocols (SSL 3.0, TLS 1.0/1.1) are deprecated and cause Error 15222.
