Your debug log is fine. However, there a a few things that could be "improved" and might be related to the issue you experience.

You distribute your Router's IP as DNS server via DHCP to your clients. You could change that to be the IP of your Pi-hole. Advantage would be that you see individual clients in your dashboard and could use the group management if needed.

You assigned an IPv6 with a global scope to your Pi-hole (2a01:XXX). This address might change, e.g. if you get a new IPv6 prefix from your ISP. If you need IPv6 within your lan, it's better to assing a ULA address.
