I have configured dnsmasq with dns-over-https via cloudflare (Issue happens even if disabled)
dnsmasq config
dhcp.cfg01411c=dnsmasq
dhcp.cfg01411c.domainneeded='1'
dhcp.cfg01411c.localise_queries='1'
dhcp.cfg01411c.rebind_protection='1'
dhcp.cfg01411c.rebind_localhost='1'
dhcp.cfg01411c.local='/lan/'
dhcp.cfg01411c.domain='lan'
dhcp.cfg01411c.expandhosts='1'
dhcp.cfg01411c.authoritative='1'
dhcp.cfg01411c.readethers='1'
dhcp.cfg01411c.leasefile='/tmp/dhcp.leases'
dhcp.cfg01411c.ednspacket_max='1232'
dhcp.cfg01411c.confdir='/tmp/dnsmasq.d'
dhcp.cfg01411c.localservice='1'
dhcp.cfg01411c.sequential_ip='1'
dhcp.cfg01411c.doh_backup_noresolv='-1'
dhcp.cfg01411c.noresolv='1'
dhcp.cfg01411c.doh_backup_server=''
dhcp.cfg01411c.server='/mask.icloud.com/' '/mask-h2.icloud.com/' '/use-application-dns.net/' '127.0.0.1#5333'
from any host if I try dig to resolve local hosts, works 1 of each 2/3 executions
