Resolve .onion pages - DNS_PROBE_FINISHED_NXDOMAIN

[MisterDeeds]

Dear all

Many thanks for the project! The deployment worked without any problems, and if I specify my Docker host as a tor proxy - it shows that I am connected via the Tor network:

I have adapted the config that other hosts from my network can also connect to it:
---
version: "2"
services:
tor-socks-proxy:
container_name: tor-socks-proxy
image: peterdavehello/tor-socks-proxy:latest
ports:
- "8853:53/udp"
- "9050:9150/tcp"
restart: unless-stopped

However, if I want to connect to an .onion page (e.g. http://duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion), I get the message "DNS_PROBE_FINISHED_NXDOMAIN"

What am I doing wrong? Thank you and best regards
