Timed out DNS connections

[DTPlayer]

Greetings. I ran into a problem that the DNS server does not process requests.

$ nslookup ifconfig.co 127.0.0.1
;; communications error to 127.0.0.1#53: timed out
;; communications error to 127.0.0.1#53: timed out
;; communications error to 127.0.0.1#53: timed out
;; no servers could be reached

docker-compose.yml

services:
    sniDust:
        container_name: sniDust
        environment:
            - 'ALLOWED_CLIENTS=127.0.0.1/32'
            - 'EXTERNAL_IP=64.*.*.*'
            - TZ=Europe/Berlin
        ports:
            - '443:8443'
            - '80:8080'

        image: 'ghcr.io/seji64/snidust:main'
        restart: unless-stopped

Everything works well inside the container. What could be the problem when transferring everything from Docker to the system? Thank you in advance for your reply.

hm 127.0.0.1 is not correct in this case. 127.0.0.1 is the src ip if running dig inside the container. you test the query from the docker host? then you probably need something like 172.17.0.0/16 (docker default).

Ok, on server dns working, but in my pc dns timeout(ip address in allowed clients is correct) With 0.0.0.0/0 in allowed clients from PC, I get timeout too Port 53 has open in server

I fix that. We are a router block DNS packets)
