중국 대륙과 같은 특수 지역에서 운영 중이신가요?

호스트의 DNS를 확인한 후 Docker 내의 DNS를 확인해 보시기 바랍니다.

호스트의 DNS 확인:

```plaintext
resolvectl status|egrep Servers
nslookup github.com

```

Docker 내의 DNS 확인

```plaintext
docker exec -it app bash -c "cat /etc/resolv.conf"
docker exec -it app bash -c "wget -O - -v https://github.com/discourse/logster.git/ |wc"

```
