Load Generator not available

Hi All

I have 3 Remote Load generator configured to Agent port 7200

on my controller i have Agent port as 7100 for embedded generator - if I change it to 7200 it does not work at all

Now on controller - Remote Load Generators are appearing Green but when i try to Run Check User path - it says Localhost is Busy

and Localhost still shows 7100 - i did changes in Config File the Agent properties also controller properties but seems like i did not matched the right combination

Anyone knows or have solved this ?

NOTE: port for this project is 7200 only
