Can't pass the license check in Single Mailbox Recovery

I installed the SMBR on a Windows 2012 R2 VM. But I'm unable to pass the license check unter About -> License Info

Tried the cluster management and node ip's unter "Storage appliancename or IP address" but I alway get the following error:

"Netapp storage appliance not found. Verify the specified storage appliance is accessible and try again"

It works with the older 7-Mode system. But because the 7-Mode system will go offline in a few month I installed now a new SMBR VM.

All the Webserver services are enabled on cluster and the vserver.
