Hi @Volkan Sözeri

Thank you for reaching Microsoft Q&A.

I am sorry for the inconvenience you have faced while you are configuring the Entra connect.

It might be issue with the TLS 1.2 is not enabled in the .NET framework

Could you please run the below PowerShell script to enforce TLS 1.2.

PowerShell script to enable TLS 1.2

Before installing, please read and verify the Prerequisites for Microsoft Entra Connect.

If your Hybrid Identity Administrators have MFA enabled, the URL https://secure.aadcdn.microsoftonline-p.com must be in the trusted sites list. You're prompted to add this site to the trusted sites list when you're prompted for an MFA challenge, and it hasn't been added before. You can use Internet Explorer to add it to your trusted sites.

If the issue persists, please refer the below article
