Windows Admin Center - Cluster Creation Extension 1.2 - Local Admin Group issue

Hi all and happy new year 2020,

 

I tried to create a simple cluster with 2 VM.

Both are WS2019 DC and domain joined with FO Cluster features installed.

My Windows Admin Center is on another joined server with WS2019STD.

All servers are found and I can manage them all with my domain admin account.

But I cannot create a cluster via Windows Admin Center.

I always get this error : "The provided domain user account credentials are not in the local Administrators group…". (cf: joined picture)

So I Added the domain admin to local admin group. But no change. Always stuck on the same error.

 

Anyone could help please ?

 

Thanks a lot !
