Hyper-V 2016 3-Node Cluster - Getting 'Your credentials did not work" connecting to Roles on one node but not the others.

Hi - I have a 2016 Hyper-V failover cluster using a cluster storage volume on a Dell SAN. Node 1 and 2 were part of an original installation and I can do live migrations between the two and I can log onto either node, open Failover Cluster Manager and connect to any hyper-v role on Node 1 and 2. Recently added Node 3. Processor was different than Node 1 and 2 but I updated Node 1 and 2 processors. Validate Cluster and all is good (few Roles Integration Services aren't updated but these aren't necessarily the machines I'm having problems with.) Problem 1: When I'm on Node 1 or 2 and use Failover Cluster Manager to connect to a role on Node 3, I get the message 'Your credentials did not work". Problem 2: I cannot perform live migrations from Node 1 or 2 to Node 3 and vice-versa. I have compared every possible setting I can find between Nodes 1, 2 and 3 but cannot figure out why I'm having these problems. Hundreds of Google searches and reading articles have not helped me resolve this. All the Virtual Switches are named the same, firmware is all the same, tried enabling Processor Compatibility, checked permissions, etc.. During Live Migration I get the typical EventID 21502, 1205, 1069. In 21502 it says:

User "DOMAIN\WDHVCLS01$" failed to create external configuration store at 'c:\ClusterStorage\Volume1\Hyper-V\SERVERNAME' General access denied error ()x80070005.

Failed to set security info for '\?\Volume [SID]\hyper-v\servername\Virtual Machines' General access denied error (0x80070005)

You are using Kerberos authentication option for live migration which requires setting up credential delegation. The access denied might have been caused by incorrect delegation setup.

I've checked all the above and have not been able to fix anything. I've also evicted the Node 3 and joined it in again, but no luck.

Any help anyone can provide would be appreciated.
