– On a remaining WAP server, run:

simply reinstall Windows on the same hostname and rejoin it to the cluster without first removing the trust. A reused hostname with an orphaned trust will cause a “duplicate proxy” error during reconfiguration.
If your WAP cluster sits behind a load balancer (Layer 4 or Layer 7), you must remove the server from the backend pool configuration. remove web application proxy server from cluster

How to Remove a Web Application Proxy Server from a Cluster Managing a Remote Access deployment often requires scaling your infrastructure down or replacing aging nodes. When using Web Application Proxy (WAP) in a cluster, simply shutting down a server isn't enough; you must gracefully remove it to maintain the integrity of your AD FS (Active Directory Federation Services) publishing environment.
Removing a node reduces your high-availability (HA) capacity. If this is your last proxy, external users will lose access to all published applications.
Before you start, ensure you have the necessary access and that you have planned for the removal. Take note of: 1
By following these steps, you ensure that your AD FS traffic continues to flow smoothly through your remaining healthy nodes.
