Controller 4.61 and All in one do not want to communicate

Hi. can anyone help me with my diybms
i have the 4.61 controller and all in one with passive balancing
both powering on ok.
connection of comms as per picture above, the all in one is blinking 3 times, which is correct
i connected 3 cells for test.
the problem is that the controller can not communicate to the module and sais waiting for modules.
if anybody can point me to the right direction that would be helpfull

Thank you.
