Cannot Find Thumbprint by Certificatename - Keyset does not exist

I've followed the link mentioned by MS trying to import/generate certificate And uploaded it to the app registration's certificate and installed it inside the VM and modified the web.config file and also added the API permission for the application in azure but now I'm facing this issue / Keyset does not exist / can you please guide me what I've missed?

Umapathi

Create self-signed cert in CHE via PowerShell command.

New-SelfSignedCertificate -CertStoreLocation Cert:\LocalMachine\My -DnsName "CHECert" -KeyExportPolicy Exportable -HashAlgorithm sha256 -KeyLength 2048 -KeySpec Signature - Provider "Microsoft Enhanced RSA and AES Cryptographic Provider" -NotBefore (Get-Date -Year 2022 -Month 5 -Day 1) -NotAfter (Get-Date -Year 2025 -Month 12 -Day 31)

On CHE go to Manage computer certificates, expand Personal | Certificates | right-click on certificate | All-Tasks | Export. In the wizard just keep defaults and export to .CER file.

In Azure portal go to Microsoft Entra Id | App registrations on left | click New registration. Under the app registration go to Certificates and secrets and click Upload certificate. Choose the certificate .CER file you created and upload.

In the app registration Overview click Add a Redirect URI. Then click Add a platform and provide F365 Finance base URL in the top URI redirect field and click Configure.

In the app registration, click API permissions on left and then Add a permission. Choose Dynamics ERP and then Delegated permission. Make sure AX.FullAccess is checked and click Add permissions.

Click Add a permission again. Choose Microsoft Graph and click Application permissions. Expand Group and check Group.Read.All. Expand User and check User.Read.All, then click Add permissions.

You will see warnings so then click Grant admin consent for <> button.

On the CHE, go to Manage computer certificates, expand Personal | Certificates and then right-click on the certificate and choose All Tasks and then Manage Private Keys. Click Add. Type in "Network Service", click the Check Names button, then OK.

Make sure Allow -> Read permission is checked and click OK.

On CHE go to K:\AosService\WebRoot\ and backup web.config file. Open the web.config in Notepad with Administrator permissions.

In the web.config, replace the value of the Aad.Realm key with the application ID/client ID value. Replace the value of the Infrastructure.S2SCertThumbprint key and the GraphApi.GraphAPIServicePrincipalCert key with the value of the installed certificate's thumbprint.
