Resolved:
Turns out 127.0.0.11 is Docker standard for container DNS. The issue was with my Umbrel host.
Some issue with my local DNS resolution. Probably due to my pi-hole installation.
The following workaround resolved all my issues:
In brief, modify the pihole docker-compose.yml
from:
---
version: '3.7'
services:
unbound:
image: mvance/unbound-rpi:1.13.0
hostname: unbound
restart: unless-stopped
ports:
- 53:53/udp
- 53:53/tcp
volumes: [...]

version: '3.7'
services:
unbound:
image: mvance/unbound-rpi:1.13.0
hostname: unbound
restart: unless-stopped
ports:
- 192.168.1.30:53:53/udp
- 192.168.1.30:53:53/tcp
volumes: [...]
Where 192.168.1.30
is a ip address of the docker host.
