this might fail as switching the remote connection mode does not wait for 10 seconds for the new connections to be established. I think we should adapt the waiting logic to take this into account.

So you want me to just always wait? Setting aside the mode, any change to a remote cluster config through settings will involve the connection being torn down and rebuilt.

I made a change in remote cluster service to always wait. The update method will complete the listener before returning if the connection is being destroyed or unchanged (meaning no wait.)
