Metal PtP link problem

RouterOS Wireless Networking
1

Hello, folks.

I have a clear nice link about 3 km with relatively clean spectrum.

The problem is that 2 metals with 34 dbi grid antennas could not establish a connection.
Here comes configs

On Point1 logs I see

I tried different frequencies, wireless/wireless-fp packages, different power levels - same issue.

Any suggestions ?

Disable security and set channel to auto on AP, default on station. If is it working you have an starting point of discover your mistake.
Btw verify this: connect-list, better disable it.

Connect-list is empty.
Same problem with disabled security.

Reset configuration with no defaults. Then rebuild.
