(attn @mengzhuo @oiooj)

Curiously, I haven't seen any such errors on linux-mips64le-mengzhuo. 🤔

[oiooj]

Thanks @bcmills，It seems that the HTTPS PROXY not stable，Can you add proxy.golang.com.cn into NO PROXY lists？ @mengzhuo

[bcmills]

@oiooj, I don't think the Go coordinator sets HTTPS_PROXY or HTTP_PROXY for these builders — maybe that's something @mengzhuo can tweak in the local environment?

[mengzhuo]

Updates:

goproxy.io will redirect to proxy.golang.com.cn, I've updated unmatched and will tweak WSL today.

---

I've set the NO_PROXY on unmatched but it seems not working?

Updates:

Proxy setting of wsl and unmatched builders had been updated to proxy.golang.com.cn with NO_PROXY=*.cn

[bcmills]

Thanks! I'll keep an eye out during triage — so far it's looking promising.
