Event 1070 FailoverClustering error code 1629

Hello,

I built a cluster and trying to add a second node.  Both servers are on two different subnets, they reached each other properly.

When I try to add the second server as a node, it times out, and in Windows logs, there is an event 1070 which shows "The node failed to join failover cluster 'DAG-Tech' due to error code '1629'."

There is another event 7024, with this description "

The "Data of wrong type" corresponds to the meaning of the error code 1629.

How to resolve?  What data is wrong?

Thanks, Dominic
