Environment

VMware vCloud Availability 3.0.x

Cause

This issue can occur when you have IPv6 is enabled on the PSC, the PSCs FQDN resolves to its IPv6 address, and the on-premises vCloud Availability appliance is not configured to communicate over IPv6.

Resolution

To resolve this issue, register the on-premises vCloud Availability appliance to the vSphere Lookup Service using the IPv4 address of the PSC or disable IPv6 on the PSC.

Additional Information

• For more information on making network changes to the PSC, see the Configure the DNS, IP Address, and Proxy Settings section of the vSphere documentation.
• For Windows based PSC, you can disable IPv6 through the Windows registry. For more information on how to do this, see Guidance for configuring IPv6 in Windows for advanced users.
