    Hi @lalajee

    Thank you for asking this question on the **Microsoft Q&A Platform. **

    First, you must ensure that the user from your Azure AD has the correct password and that the user cannot have the MFA active.

    Also, I recommend you try a fresh installation of Azure AD Connect.

    Let me know how it goes...

    Hope this helps,
    Carlos Solís Salazar

    @julien Hardy
    we ran into the same issue today.
    we first ran the powershell script (as admin) https://video2.skills-academy.com/en-us/entra/identity/hybrid/connect/reference-connect-tls-enforcement#powershell-script-to-check-tls-12

    then we ran via powershell as admin
    c:\Program Files\Microsoft Azure Active Directory Connect tabbed to the executable
    .\AzureADConnect.ext /interactiveauth

    Hope that helps? we are now waiting for it to fully sync over, but we overcame the issue you had

    I've solved the problem, it was due to TLS 1.2
