Failover Cluster Validation Stuck

Hello everyone,

I'm having the following problem when creating a 2-node HA cluster (Server 2025) using the Windows Admin Center (Gateway). Up to the point "Validate Cluster" everything worked fine. Unfortunately, the process gets stuck at "1% Gathering data about nodes". 

However, I can confirm that the cluster report was successfully created on the first node without any errors.

Has anyone else seen something similar and, ideally, have a solution for me?

I checked the following: 

Permissions such as CredSSP, Remote Powershell and WinRM are correctly implemented on the WAC gateway and nodes.

Manually execute the PowerShell command successfully: 

Test-Cluster -Node $ServerList -Include "Storage Spaces Direct", "Inventory", "System Configuration"
