DHCPREQUEST DHCPNAK loop in pihole.log

Expected Behaviour:

[Clean log file without continuous dhcp requests]

Actual Behaviour:

[Loop in tail pihole.log that looks like this]
00:00:19 dnsmasq-dhcp[883]: DHCPREQUEST(eth0) 192.168.0.2 00:17:88:46:e8:a0
00:00:19 dnsmasq-dhcp[883]: DHCPNAK(eth0) 192.168.0.2 00:17:88:46:e8:a0 wrong server-ID

Debug Token:

[lio43bgz1f]

Everything else seems to be working fine does anyone have any idea what could be causing this?

Those NAK's could be caused by two or more DHCP servers active on the network.
Have you checked all your devices, routers, AP's, Pi-hole's own DHCP service etc to make sure only one DHCP server is active in your network ?

Power cycle the Phillips light bulb :wink:

What is this device? Your router is .1, your Pi-Hole is .100.

The other thing I note from your debug log - you are advertising DHCP addresses across a large range, including the IP of your Pi-Hole. You might want to shorten this range and not overlap your Pi address (unless you expect 252 clients).

DHCP_ACTIVE=true
DHCP_START=192.168.0.2
DHCP_END=192.168.0.254
DHCP_ROUTER=192.168.0.1
DHCP_LEASETIME=24
PIHOLE_DOMAIN=lan
DHCP_IPv6=true

Haha Ok I so I hadn't installed the light bulbs but I did install the network hub and totally forgot about it. I
also adjusted the DHCP range down to a reasonable length. Thank you guys so much for your help. How did you know it was a Phillips device though? I couldn't figure it out.:tired_face:
