Error: Cannot read properties of undefined (reading 'nodeName')

Occasional Visitor

Hello,

 

I'm trying out Windows Admin Center I'm running in an HA cluster. I seem to constantly get these errors when moving between sections.  "Error: Cannot read properties of undefined (reading 'nodeName')"  Sometimes the pages will load and sometimes they won't.  Any help would be appreciated.

@mbeckler - I had a similar issue today with a 2-node ASHCI 21H2 cluster with this error when trying to connect via WAC:  "Error: Cannot read properties of undefined (reading 'nodeName')"

Turns out one of the nodes was having issues and wasn't able to connect to it with WMI and Hyper-V Manager wasn't able to connect. I rebooted the node and it resolved my issue. Perhaps check for a Node that isn't responsive and reboot it.

Hope this helps.
