While running the configuration wizard to register your PVS Server against Citrix Cloud you are greeted by an unexpected console error.  "Error Registering Server, Sequence contains no matching element" as shown below:



The PVS configwizard.log file will show you this exception:

ERROR:RegisterSingleTenantKey: unexpected exception: Sequence contains no matching element    [ConfigWizardKrsModule.cs(795): HandleException]


 

On the PVS Server network interface communicating with Citrix Cloud enable the IPv6 protocol.

Problem Cause

The PVS Server to Citrix Cloud registration process uses PVS machine system information including its self assigned or DHCP assigned IPv6 address.  In order to register a PVS Server running 2303 with Citrix Cloud an IPv6 address must be assigned to the NIC communicating with Cloud.  IPv6 can be disabled on the PVS Server after registration is complete if the requirement arises.  

 

This IPv6 requirement is under further review and subject to change.
