First, your can change your repository of alpine (the available alpine repository in china,

Sec maybe the repo empty, try https://mirrors.tuna.tsinghua.edu.cn/alpine/edge/

1. Edit /etc/apk/repositories

2. Remove the old repo (dl-cdn..../edge) and replace to the repo i told at up

3. Try again

You should see that I pinged Baidu just now, Baidu is the largest search engine in China, so it is impossible for the ping to time out, so it is useless to replace the mirror.

The official alpine mirror can be connected in China, and there should be no dns parsing problems.

China has been actively blocking DNS servers not located in China since forever, and the default Cloudflare DNS is among those blocked.

I don't think we have better ways other than manually editing /etc/resolv.conf, unless there is somehow a way to forward this to the Android resolver/local network resolver?
