Printer broadcasting issue?

After the last update of cnMaestro, I have major problems with printers?!
Maybe it’s a coincidence but it hasn’t happened before.
Namely, the printer broadcast does not work (HP, Epson), it does not see printers on the network and cannot find them Printing over TCP ports working well). Connecting to another network outside of Cambium solves the problem. All HP and Epson software are unable to find printer and unable to monitor existing prnters.

This happens on software 4.2.3.1-r7 and on wifi6 version 6.6.x.x.
Can someone take a look at this?
