The VMware HCX plugin in vCenter may experience loading issues where the virtual machine inventory fails to load, displaying a perpetual "Loading data, please wait" message. This can occur after upgrading to newer versions of HCX, particularly affecting vSphere environments with the HCX plugin installed. Users may need to access the HCX Manager directly as a temporary workaround.
Common symptoms include
Indefinite loading screen in the HCX plugin interface
VM inventory not displaying
Plugin becoming unresponsive
Inconsistent behavior across environments
Environment
HCX
vSphere environments with the HCX plugin installed
Cause
Several factors can contribute to these plugin loading issues
Plugin state inconsistency following HCX upgrades
vCenter integration or communication disruptions
Service state synchronization problems between HCX and vCenter
Version compatibility mismatches between HCX and vCenter components
Cache or session state issues in the plugin
Network connectivity or firewall rules affecting plugin-to-service communication
Resolution
Immediate Workaround
Access HCX Manager directly through its web interface instead of the vSphere plugin
This ensures continued access to HCX functionality while resolving the plugin issues
Long-term Resolution
Component Updates
Ensure all HCX components are at the latest supported version
Maintain consistent versions across all environments
Schedule regular maintenance windows for updates
Reboot management appliances regularly
