You could upgrade HCC to a newer release (if you don't have the latest) see "vCenter communication resiliency" in:

If HCC upgrade doesn't help, contact Support.

Hi, elementx.

We resolved this problem by hcc upgrade(mnode upgrade).

("One or more vCenter instances cannot be reached, causing some information to be unavailable.")

Thank you so much.

We could not see cluster information before upgrade.

But after upgrade we could see cluster information and no alerts on GUI.

Thank you for your coporation.
