Hello we were trying to set up a cluster with Azure Stack HCI Hyperconverged with2 dell T320 server with azure hci operating system and a normal PC with windows server 2019 and admin center on it. They are all on the same site. The windows server 2019 is a domain controller. The 3 machines are connected with the same account, and it is well in the group Windows Admin Center CredSSP Admin. All servers are up to date. Each time we want to create the cluster with the create button we have this error. We have followed this documentation but nothing happens : https://video2.skills-academy.com/en-us/azure-stack/hci/manage/troubleshoot-credssp

    Hi @Savary Corentin , Thanks for posting your query on Microsoft Q&A.

    It looks like your issue could be similar to the one described under CredSSP in the Known Issues document
    It says: The CredSSP session endpoint permission issue is a common CredSSP error that can be seen when Windows Admin Center runs on Windows client machines. This issue is widely seen when the user who is using Windows Admin Center isn't the same user who installed Windows Admin Center on the client machine.

    To mitigate this problem, we have introduced the Windows Admin Center CredSSP administrators' group. The user facing this problem should be added to this group and then relogin to the desktop computer running Windows Admin Center.
    Solution: Add your user account to the "Windows Admin Center CredSSP Administrators" group on your local PC, sign out on your PC, and then sign back in.

    Other documents to refer :

    Get started with Azure Stack HCI and Windows Admin Center

    If this doesn't help or you have already tried this, please let me know in the comments.
    In that case, we would need to do deeper troubleshooting with the help of a support engineer with access to the backend who can also setup a call with you for live investigation. I will enable a support request for you, if you do not have the ability to create a support request.

    We are having the same issue here when trying to create the Cluster. Waiting for the answer to see if we can have a solution about that. In the meantime, we´ll try to follow the steps mentioned in the above answer.
