We have HA platform v8 and use config server primary/backup.
However recently when we lost framework host, applications such as GAD failed to connect with backup config server.
I think the issue is failure for config server backup to become primary correctly.
but it has been recommended we use config server proxy however not such what the benefit would be?
We are a single tenant environment.
Kubig is absolutely correct. There are many benefits to using Config Server Proxies. Particularly if you have a large environment. CS Proxy will reduce the load on the main config server. And if config server goes down, the clients connected to CS Proxies will still have read access to data so the impact to the environment as a whole is lessened.
