The issue I am facing:
If I want to use Pihole I have to use the built-in DCHP because my router does not allow me to set DNS servers. And it works fine... until the router is restarted or sometimes randomly(maybe when leases expire?). When that happens in most cases I lose internet connection, I still have access to the local network and can ping/ssh my PIs but not outside connection.
Also even when I have internet services behind Caddy reverse proxy + cloudflare are unreachable, no hits on caddy logs. Services using cloudflare tunneling work fine.
Other rare cases:
Internet / No local network
I can access the Internet but not the local network, all devices can access the Internet. In some cases, I noticed that no ipv4 IP was assigned to any of the devices even if my laptop and 2 PIs have static IPs, instead, they all had only ipv6 IPs. Could not even access the router.
No Internet / Partial local network?
Similar with the issue above however, at that time my Laptop did not have a static ip just had a ipv6 ip and was completely locked out of the network while the PI's had an ipv4 and could ping each other.
Things I tried:
Enabled ipv6 in pihole, upstream servers : unbound recursive, google & quad9 with and w/o ipv6, restarting dns server after router reboot, flushing network table, reload config.
Anything I could think of and I could find on google.
I have been at this for 2 days now, pressed every button and ticked every box nothing seems to fix it.
I have also tried Adguard and have the same issue both with docker and w/o docker install.

What I have changed since installing Pi-hole:
I moved pihole to docker & added unbound
Edit: Added debug log for fresh install
