Error: Cannot Read Properties of undefined (reading:'nodeName')
Windows Admin Center running on Cluster : Version 2110 Build 1.3.2111.01001 Failover Cluster Tools 2.20.0
When moving around the sections I get the error in very different sections. Sometimes pages will not load and sometimes they do. Dashboard in the cluster section does not load at all.
@Mbeckler This usually happens when the cluster connection needs to be re-authenticated. Do you have single-sign on enabled?
Hello, I am not using single sign on right now.
So originally I removed the cluster and re-added it and was still experiencing this error. This time I want to "manage as" and re-entered my credentials after adding it and it is functioning at the moment. I had attempted that first but I think removing/re-adding then redoing credentials maybe is what took care of it.
Thanks
So just as another point of data. If I leave the WAC site and then come back to it, it still says managing as my admin user that I want to use but if I click on the server I get all the aforementioned errors but none about credentials or log in. At that point I have go back and use manageas before it work again.
Thank you for providing this insight. If you do start using single-sign on, please let me know if you still experience these issues.
Hello! A follow up on this. Did you start using single sign on? And do you continue to experience this issue? Kind regards

It does not happen with single sign on. However I haven't gotten single sign on to work properly either but that is another issue. I ran the command to delegate Kerberos but the cluster doesn't seem to like it and won't authenticate with SSO, but even if I enter the username password I do not get as many errors as I was getting.

I attempted to start using single sign-on but I can't seem to get it work, but I doubt that is a bug. I think it must be an issue with Kerberos constrained delegation and how it works with running WAC in HA from a cluster.
