Current master fails to reach over the network...

Environment

MacoS Catalina and Linux CentOS 8. Cabal-3.2.0.0, ghc-8.8.3. Current master of this repo.

$ ~/.ghcup/bin/ghcup debug-info
DebugInfo {diBaseDir = "/Users/ur20980/.ghcup", diBinDir = "/Users/ur20980/.ghcup/bin", diGHCDir = "/Users/ur20980/.ghcup/ghc", diCacheDir = "/Users/ur20980/.ghcup/cache", diArch = A_64, diPlatform = PlatformResult {_platform = Darwin, _distroVersion = Just (General (Version {_vEpoch = Nothing, _vChunks = [[Digits 10],[Digits 15]], _vRel = []}))}}
$ ~/.ghcup/bin/ghcup numeric-version
0.1.4$ 
$

Problem

On all of my platforms, ghcup built from the master completely fails on the network access:

$ ~/.cabal/bin/ghcup -v debug-info
[ Debug ] Receiving download info from: GHCupURL
[ Debug ] Unable to get/parse Last-Modified header
ghcup: SSL_connect: resource vanished (Connection reset by peer)
$ 

I thought we already talked about the [un]reasonable-ness of the need to reach over the Internet to answer simple questions, like "what my config is?", "what kind of system am I running on?", and "what is my version?"

Since there's no more of debugging output, the above is all I can tell you.

The binary provided via $ ghcup upgrade seems functional, the binary built from the current master is not.
