Change one of the port from Coordinator systray | right click | coordinator configuration | Ports TAB and change one of the port for Client or Agent by increment the value by 2.
For example if the ports are
Client Port: 8122
Agent Port: 8122
Change one of the ports to 8124
By default the Coordinator will dynamically select ports in the following sequence
Client Port: xxxx2
Public SDK Port: xxxx3
Agent Port: xxxx4
Setting the port back to 0 on the Coordinator Configuration does not reset the value to default.
