Symptoms

When a vSphere environment is being upgraded to version 8.0, CloudLink 7.1.x (or a previous version) as a Key Provider is not supported.
Although vCenter can be upgraded to 8.0 and still show connectivity to CloudLink 7.1.x, the ESXi hosts will be locked after the upgrade. CloudLink must be upgraded to version 8.0 or later to address these issues. 

The recommended process is to upgrade CloudLink to version 8.0 or later first, then upgrade the vSphere environment to version 8.0.

Cause

ESXi hosts at version 8.0 do not work with CloudLink 7.1.x. This is because CloudLink 7.1.x does not support the TLS 1.3 protocol that the ESXi hosts. CloudLink 8.0.x and later versions support this protocol.

Resolution

To resolve this issue, upgrade CloudLink to 8.0 or later versions.
Check the upgrade path by reviewing the CloudLink 8.0 Release Notes.
