Container keeps restarting - Unable to resolve github.com

[itsRems]

Issue Description: Hi. I'm having in issue while starting lancache-dns on a static ip. Apparently the dns is screwed up and the lancache dns is not able to update its server list from github, although it's accessible from the host and I setup the UPSTREAM_DNS.

Docker Run Command:

sudo docker run --restart unless-stopped --name lancache-dns --detach -p 192.168.1.20:53:53/udp -e USE_GENERIC_CACHE=true -e LANCACHE_IP=192.168.1.20 -e UPSTREAM_DNS=8.8.8.8 lancachenet/lancache-dns:latest

Docker Container Output:

Executing hook /hooks/entrypoint-pre.d/10_generate_config.sh
/opt/cache-domains /scripts
fatal: unable to access 'https://github.com/uklans/cache-domains.git/': Could not resolve host: github.com

Can you try the following from the docker host nslookup GitHub.com 8.8.8.8

Can you try the following from the docker host nslookup GitHub.com 8.8.8.8

Works!

nslookup github.com 8.8.8.8
Server:         8.8.8.8
Address:        8.8.8.8#53

Non-authoritative answer:
Name:   github.com
Address: 140.82.114.3

That's my big problem w/this. It's just... supposed to work but it doesn't

Could you tell me which operating system your lancache-dns runs on? @itsRems

I had a problem like this (ubuntu 18.04) and my problem was the systemd-resolved process. Indeed I managed to make everything work by performing these manipulations:

sudo systemctl disable systemd-resolved sudo systemctl stop systemd-resolved -> edit /etc/resolv.conf with the DNS server of your choice (this allows your server to make resolutions even if the lancache-dns docker turns on port 53).

This is my docker command: docker run --restart unless-stopped --detach --name lancache-dns -p 53:53/udp -e USE_GENERIC_CACHE=true -e LANCACHE_IP=$MyIpAdress -e UPSTREAM_DNS="1.1.1.1; 1.0.0.1 ;8.8.8.8; 8.8.4.4" lancachenet/lancache-dns:latest

Indeed I determined that the process prevented the lancache-dns docker from working properly, it restarted constantly.

Been having similar issues to this with macOS as the docker host. Sometimes lancache-dns works, sometimes it can't resolve GitHub.com and sometimes it does initially then stops after some time.

I tried with 1.1.1.1 and 8.8.8.8 separately which didn't work but now the combination of "1.1.1.1; 1.0.0.1; 8.8.8.8; 8.8.4.4" seems to have done the trick thanks @Atomis70
