Moving DHCP lease behavior from DDWRT to piHole. Don't want to add 20+ listings through the GUI. Manually updated the 04-* file in /etc/dnsmasq.d/ with my entries.
DNS immediately stops working afterwards. Deleted that file and rebooted and DNS/FTL works again.
Sorry I'm remote and dont have this
A likely problem is a syntax or line feed/break problem in that file.
I was thinking the same thing but this morning i've done some more troubleshooting and i'm still stumped.
I was manually adding in my listings through the GUI .. got about halfway through and noticed DNS/FTL had stopped again. I have to delete the conf file and disable DHCP, reboot and DNS works again. I tried manually adding every single entry in again .. got through the whole list and everything was still up and running. I rebooted just to be sure all would work and sure enough when it came back up DNS/FTL was borked again. I have to remove the CONF file, disable DHCP and reboot for it to work like normal again. I copied the conf file (which was created when I manually added each entry to the GUI) out of the dnsmasq.d directory and i'm comparing it to the one I added via cmd and they are identical except for a few entries I didnt include. syntax looks legit. Is there a limit to how many hosts you can add or something? I dont understand the correlation between the DHCP static leases and DNS going up / down.
Checking the logs for the error is a much more direct path to find out what the error is:
journalctl -u pihole-FTL --full --no-pager
cat /var/log/pihole-FTL.log
cat /var/log/pihole.log
If you post the configuration file, we can double check.
I replaced the actual hostnames with hostnames below. None of my hostnames have spaces. Some have dashes but no spaces.

Check the output of the commands I posted for the error which causes dnsmasq to fail.
Not seeing anything jump out at me.
I didnt even enable DHCP this time. simply manually added the entries into the file via nano.
Restarted the system and DNS/FTL is down. did the journalctl command and then cat'd the two logs.
This log should have entries from after i added the DHCP entries to the file as well as rebooting after removing the file again (which does allow DNS/FTL to show as enabled in the dashboard again)

I cat'd the second log, but its got A LOT of stuff in it. Is there something in particular i should be looking for / grepping for?
what about sudo systemctl status pihole-FTL.service when the outage occurs ?
ok .. so mega weird. I copied the 04 conf file back to the /etc/dnsmasq.d/ directory and ... everything is working now? I've now disabled dhcp on my DDWRT router. Added the piholes IP as the first entry to the DNS order (in DDWRT) and kept the DDWRT routers IP as the dns server under setup.
I had some dnsmasq entries to forward certain hostnames on my domain to local IP's such as my router and my two NAS's, but that no longer works. I've added them into the /etc/hosts files on the pihole but i'm assuming i'll need to replicate the additional dnsmasq options I had on the DDWRT router somewhere within pihole? I guess I should start a new thread.
If the issue re-surfaces, run the command above and it will tell you where the error is ...
