rsc.io/pdf@v0.1.1: Get "https://proxy.golang.com.cn/rsc.io/pdf/@v/v0.1.1.mod": dial tcp: lookup proxy.golang.com.cn: i/o timeout

Given that they both occurred at exactly the same time, could just be a transient issue.

which DNS the builder using now? It seems that you can't connect the DNS server.

FYI /etc/systemd/resolved.conf

These issues are about builder's HTTP PROXY, it's a local network issue.

[heschi]

Are there any plans to fix this? It's ongoing.

[mengzhuo]

I had changed the proxy into goproxy.cn, let's see if it works.
