AImesh node requests dhcp, but never receives one...

[Pergola Fabio]

Hi, running an AX88u, 3004.88.1 , one of my ac86u nodes, sometimes goes offline , at that point my syslog is flooded like these below, reconnecting cable doesnt work, rebooting the node doesnt work
only fix is to reboot my router? why is that?
