Cause

WCP service on vCenter Server is not in a healthy state.

Resolution

1. Apply the resolution section of this KB:
   Remediation of host fails with health check failure
   If the error persists even after restarting the WCP service as described in the above knowledge base article, please proceed to Step 2.
   
   
2. Run though the script as per below KB and ensure that the vpxd-extension user isn't missing any SSO group permissions.
   Fixing missing SSO Group Memberships for vSphere Solution Users with the solution_users_fixer script
   Then try the upgrade pre-check.
   If it still fails , then proceed to step 3.
   
   

3. You can try this step ONLY if you are NOT using VKS/TKGS/Tanzu in this environment.
   If you are Not using VKS/TKGS/Tanzu, then please disable the health check for wcp to allow the patch.
   You can do this by editing the vci-integrity.xml file.
   Here is how to do it:

   SSH into the vCenter Server using root credentials.
   Stop the vLCM Update Manager service:
   service-control --stop updatemgr
   Back up the vLCM configuration file (vci-integrity.xml):
   cp /usr/lib/vmware-updatemgr/bin/vci-integrity.xml /usr/lib/vmware-updatemgr/bin/vci-integrity.bak
   Edit the configuration file:
   vi /usr/lib/vmware-updatemgr/bin/vci-integrity.xml
 
<EhpConfig>
    <ExternalProviders>
      <eam>
        <enabled>true</enabled>
      </eam>
      <nsxt_rest>
        <enabled>true</enabled>
      </nsxt_rest>
      <pod>
        <enabled>true</enabled>
      </pod>
      <vpxd>
        <enabled>true</enabled>
      </vpxd>
      <wcp>
        <enabled>true</enabled> <<<<<<<<<<<<<<
      </wcp>
    </ExternalProviders>

   Please change it to false :  <enabled>false</enabled>
   Save the file and restart the Update Manager service:
   service-control --start updatemgr
   Once the service is restarted, log in to vCenter and reattempt the pre-check and upgrade. 

   When all the upgrades are successfully completed, please re-enable the health check for wcp.
