Microsoft Azure AD Connect / Entra Connect Setup broken again.... (2.3.8.0)

Question

I have now tried to create a domain controller via Azure, but after 7x redeploying I slowly don't know what is going on... the credentials are correct, I have followed all the tips and tricks of spiceworks including the trick of the copy/paste model, modellog.

However, I keep getting the error: "Unable to install the Synchronisation Service. LocalDB powershell operation failed on ADSync Bootstrap service: Enable-ADSyncBootstrapLocalDBInstance Further details can be found in the application and system event logs.

LocalDB powershell operation failed on ADSync Bootstrap service: Enable-ADSyncBootstrapLocalDBInstance

And now we are getting in Trouble because the AVD Project is right now on hold.

Issue: Getting error while installing AD connect in your environment. Error: "Unable to install the Synchronisation Service. LocalDB powershell operation failed on ADSync Bootstrap service: Enable-ADSyncBootstrapLocalDBInstance Further details can be found in the application and system event logs.

Solution: There was an issue with DNS in West Europe zone. Once DNS issue was solved, issue got resolved now.

While installing AD connect usually the server tries to connect to domain controllers for setting some permissions on the domain accounts. Since there was an issue with DNS, AD connect server was unable to contact domain controllers.
