@mstaack , welcome to thecommunity!

Can you describe your exact issue?
Yeah so I connect via WiFi. I get an ipv6 address but no ipv4 address. Same for lan cable connection. But when I issue a dnsmasq restart it all starts to work fine.
Could it be some kind of race condition?
Cheers Max
Is there anything in the logs regarding dnsmasq right after the reboot?logread -e dnsmasq
i noticed i get a ipv4 address for a second.. then its gone...

this entry seems suspicious:Wed Jul 1 17:11:19 2020 daemon.warn dnsmasq[799]: no servers found in /tmp/resolv.conf.auto, will retry
also one note...i use a 4g lte stick as wan/uplink... which takes a minute or so to enumerate... might be this an issue?

That is a warning, should not be a reason to crash the dnsmasq.
ps wwww | grep -i dnsmasq
