Error #66 for no apparent reason

Been having error #66 on my system for quite some time now.. can't get rid of it, and it always seems to appear either early morning or early evening. Dawn and dusk..
I have 3 x 150/70 mppt running 5 different solar arrays connected into the 3 mppt's and 1 24v battery set, and a 5kw multiplus paired with a CCGX and BMv 712 all have identical settings. All are running latest firmware. Almost everyday, if not every other day I gett #66 error.. its driving me nuts !!!!
Any ideas .... anybody?...

Nope.. I've checked every single setting on all 3 controllers.. All are set exactly the same and all are running latest firmware.

Bonjour

Information 66 - Incompatible device
The controller is being paralleled to another controller that has different settings and/or a different charge algorithm.
Make sure all settings are the same and update firmware on all  chargers to the latest version

do all regulators have the same setting?
