Hui Kraishak, The first thing I see is that your failover configs aren't exactly the same. They have two differences that I see:
"max-unacked-clients": 5, vs "max-unacked-clients": 0, and "url": "http://192.168.0.169:8000/", vs "url": "http://192.168.0.126:8000/", You really want those configurations to be the same except the "this-server-name": portion. I also see that the "url": "http://192.168.0.169:8000/", on the primary (in the standby server slot) does not match what you are listening to in your control agent on the standby server: "http-host": "192.168.0.126", "http-port": 8000, I imagine if you fix that typo, it will begin to work.
