Metal 5shpn problem joining to any wireless AP

Hi all.
I have a new struggle setting up a 6Km ptp link using a pair of Mikrotik Metal 5shpn and 2 parabolic 30db kenbotong antenna in a
clean eye view …
signal on the station side is -69 an noise is -49 …
BUT…
all i got is :
authentication time out !
so i changed the modes between this 2 and i found out that
one of the devices ( AP device ) cannot connect to any wireles AP at all and the other ( station device ) can easily
join any wireless aps …

this two are not going to join each other on any condition … any security profile … and not even an OPEN security…
so what I did :

  1. changing band and freq
  2. changing security profile
  3. changing antenna with flat and dish and grid
  4. limiting tx power from 30 to 20 to 17 to 15
  5. update os version to 6.15

by the way after 8 years of setting up wifi devices at last im screwed bad…
any idea ?

ps: wifi logs only show : failed to join … by default connecting to strongest …
