Issue/Introduction

• vCenter displays a "host is not in compliance" message for the affected ESXi host.
• NSX manager reports error : Error: Timeout occured while waiting for vLCM remediation task <host-uuid> com.vmware.esx.settings.clusters.software.solutions.nsx.nsx_internal to complete.

Cause

The issue is caused by vLCM detecting a mismatch between the host's current image and the compliant image configured on vLCM.
