Devices lose internet connection when setting up Pi-hole with DHCP enabled

Expected Behaviour:

Pi-hole acts as DHCP server and starts assigning IP's to devices which provides a working internet connection while my previous routers' DHCP service is disabled.

Actual Behaviour:

This works but anywhere from 5-15 minutes after I start the DHCP service on the Pi I lose connection to the internet on all of the devices on my LAN that are using the Pi as the DHCP server. Also, the status section of the WebUI says "DNS service: not running FTL: offline" and when I run pihole -r to repair, it gets fixed but again breaks when i go to re-enable the DHCP on the pi.

**I feel the need to say that when I do have the pi handling DHCP, my router is not, and vice versa.

Edit:

Not sure if it helps but my router is an NVG589 which doesn't support changing the DNS put does allow a "passthrough" workaround of some sorts.

(if anyone has a router that works really well with their Pi-hole please let me know what kind because I'm looking into upgrading mine and am open to suggestions.)

Debug Token:

Here's the token for the Dev's:

https://tricorder.pi-hole.net/28mvccg89h

And the Debug output for anyone else:
This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations.  This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected.  Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

It appears that FTL is not running. What are the outputs of the following:

sudo service pihole-FTL status

sudo netstat -nltup | grep 'Proto\|:53 \|:67 \|:80 \|:471'

And, why do you have your DHCP lease time set to 15 minutes? That is very short. Why not a day, a week?

I had the DHCP Lease time set low just because I had been trying to just quickly release some of the devices and this was just an initial test of running the pi as what could replace my existing setup

Please run sudo service pihole-FTL restart

Then sudo service pihole-FTL status

And upload a new debug log. Thank.s

As of running this test, I do have DHCP control enabled on the Pi and disabled on the router but am still encountering the DNS service not running and FTL offline along with the dashboard saying "Lost Connection to the API.

Debug log Output:

This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations.  This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected.  Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

You seem to have a bad config option (the message is cut off):

dnsmasq: bad dhcp-range at line 6 of /etc/dn

Check the configs in /etc/dnsmasq.d for any bad dhcp-range lines.

Sorry for the late reply and thank you for pointing out that it was cut off and it was that file it told me to go to and I did check my DHCP config and it was within normal limits (ie: /24 for my network type so 192.168.1.1-254 and subnet mask was 255.255.255.0) so I guess I don't really know what is going on now. could it be that my router is conflicting with the pi-hole?

p.s. Thanks for you guys' patience and help!

Can you share the dhcp-range settings you have? Most likely one of them is wrong syntactically.

Here is the output of sudo service pihole-FTL status when I have the pi running as my DHCP server (the other was cut off a bit):

So the file that has a bad dhcp-range at line 6 was /etc/dnsmasq.d/02-pihole-dhcp.conf which I will copy below:

###############################################################################
#  DHCP SERVER CONFIG FILE AUTOMATICALLY POPULATED BY PI-HOLE WEB INTERFACE.  #
#            ANY CHANGES MADE TO THIS FILE WILL BE LOST ON CHANGE             #
###############################################################################
dhcp-authoritative
dhcp-range=192.168.1.1,192.168.1.253,.25h
dhcp-option=option:router,192.168.1.254
dhcp-leasefile=/etc/pihole/dhcp.leases
#quiet-dhcp

domain=Pi-Hole
dhcp-rapid-commit

The ending .25h should not have a period. This is generated from the settings you entered on the web interface. Did you include a period there by accident?

No this was intentional, as i wanted my DHCP Leases to last 15 Minutes. I did not realize that this would produce issues and will correct this now and update this post on if it fixed my problems! Thank you in advance.

Options:

pi@noads:~ $ man dnsmasq
[..]
       -F,            --dhcp-range=[tag:<tag>[,tag:<tag>],][set:<tag>,]<start-
       IPv6addr>[,<end-IPv6addr>|constructor:<interface>][,<mode>][,<prefix-
       len>][,<lease time>]

              Enable  the  DHCP  server.  Addresses will be given out from the
              range <start-addr> to <end-addr>  and  from  statically  defined
              addresses  given  in  dhcp-host  options.  If  the lease time is
              given, then leases will be given for that length  of  time.  The
              lease  time  is in seconds, or minutes (eg 45m) or hours (eg 1h)
              or "infinite". If not given, the default lease time is one hour.
              The  minimum  lease  time  is  two minutes. For IPv6 ranges, the
              lease time maybe "deprecated"; this sets the preferred  lifetime
              sent  in  a  DHCP  lease  or router advertisement to zero, which
              causes clients to use other addresses,  if  available,  for  new
              connections as a prelude to renumbering.

We currently only support specifying the duration in hours.

Thank you, along with everyone who helped! I've left it running for the last 72 hours and all has been running without problems.
