I screwed up adblock-lean

Somehow I managed to get adblock-lean in a state where it comes up but does nothing . I think my testing of doh is what has caused the issue . If I start adb I do see this

No ip addresses detected for dnsmasq instance 'cfg01411c'. Using the loopback addresses.

that I dont recall seeing before .

Using latest adb on OpenWrt 23.05.5

here is my dnsmasq config

config dnsmasq
        option domainneeded '1'
        option localise_queries '1'
        option rebind_protection '1'
        option expandhosts '1'
        option authoritative '1'
        option readethers '1'
        option leasefile '/tmp/dhcp.leases'
        option localservice '1'
        option ednspacket_max '1232'
        option local '/evinrude.net/'
        option domain 'evinrude.net'
        option filterwin2k '1'
        option cachesize '10000'
        option min_cache_ttl '3600'
        option quietdhcp '1'
        option confdir '/etc/config/dnsmasq.user'
        option dnsforwardmax '500'
        list addnmount '/bin/busybox'

Hi, this notification on its own does not indicate a problem, as explained here. We will improve the wording in the next release.

Besides the notification, is there any actual issue? Any errors in system log? Also please post the output of:

service adblock-lean start
echo "config:"; cat /etc/adblock-lean/config
echo "dhcp:"; cat /etc/config/dhcp
echo "network:"; cat /etc/config/network

The issue is everything seems OK but ads not being blocked

Are you sure your clients are using your DNS ?

You forgot this part:

You have a bunch of domains assigned to same IP address in /etc/config/dhcp. I wonder if this is intentional and what's the point. Probably unrelated to adblocking.

Also please issue the command
dig google.com or nslookup google.com on the host where adblocking is not working and post the output. As @frollic alluded, probably your hosts are not using your local DNS server.

I am out for a while and will return to this on Friday .

Thanks for the quick responses

I'm marking this as 'solved' . This is on my Linux box . The issue was that both firefox and chrome were told to use dns over https thus bypassing my local dns/adblock . I'm not sure how it got turned on in Chrome but this seems to be the default setting for a new install of firefox . I verified this by removing and adding firefox . major confusion factor
