There are no devices in the network tab

Hello, I have such a problem. Previously, I had pihole 5.0 installed on raspberry pi 4 and everything was OK.

Now I installed pihole on Raspberry pi zero and here everything seems to be ok in the log, I see that different devices connect and pihole blocks unwanted sites. However, in the network tab I don't see any device using pihole. Why is this happening earlier on RPI4 everything was fine.

Give this tab time to populate. And, please post the output of this command from the Pi terminal on the Zero:

ip neigh

It has been running for several hours and nothing appears, unless it needs even more time (I think that the RPI4 devices appeared immediately.)

Result of the command

pi@Pi-Zero:~ $ ip neigh

What is the output of this command that will show the top clients for the Pi-hole:

echo ">top-clients withzero (15) >quit" | nc localhost 4711

pi@Pi-Zero:~ $ echo ">top-clients withzero (15) >quit" | nc localhost 4711

Hmm...

Clear the browser cache, restart the browser and reload that page.

Unfortunately, it also did nothing. I tried on several browsers and at least on two computers

From the admin GUI > Settings > System > Danger Zone , flush the network table and give it some time to repopulate.

I received such an error

e[K [✗] Failed to truncate network_addresses table
Database location: /etc/pihole/pihole-FTL.db
Output: Error: no such table: network_addresses

This indicates that the long term database may be damaged. Do the following to move this to a new location and start with a fresh database:

sudo service pihole-FTL stop

sudo mv /etc/pihole/pihole-FTL.db /etc/pihole/pihole-FTL-old.db

sudo service pihole-FTL start

If this clears up the problem and you don't need anything from the old database, then remove it

sudo rm /etc/pihole/pihole-FTL-old.db

Many thanks it helped.

Such a cosmetic, but why doesn't it display the host name even though in DHCP the addresses are permanently assigned and the host names are given ??

Was the device active recently? I think they must be on (and actively doing requests) so Pi-hole can pick them up. Also, do you use the DHCP server of your router or the one provided by Pi-hole? If former, did you specify your router as conditional forwarding target?

devices are active all the time and send queries. I am using the DHCP server provided by pihole. I did not specify the router as a conditional purpose of provisioning - how should it be done ??
