C5c turn off the lan port

Greetings, I have the following problem, I currently use an EdgeSwitch Poe Ubnt, the cuel turns on all my antennas, including several mikrotik, I have a link with two C5c ptp with 30dbi dishes, the problem is that recently the Lan synchronization began to show failures , every few hours synchronization is lost and communication between my Ap and the switch is lost and therefore my connection drops, I don’t know why, I already tried with all the speeds and it is the same problem, I clarify that I already used the poe that brings the radio and this continues to happen. It seems strange to me because it stops failing when I change the Ap to another switch that is not Ubnt. I already tested cables and everything is fine.
