Julia 1.6 libcurl firewall download issue: Windows Schannel certificate revocation check failure

General Usage
8

Hey,

I just removed my 1.5.3 julia to install the new 1.6 on a window machine behind a proxy.

For some reasons Pkg cannot download artifacts anymore:

(@v1.6) pkg> add Distributions
   Updating registry at `C:\Users\u009192\.julia\registries\General`
   Updating git-repo `https://github.com/JuliaRegistries/General.git`
  Resolving package versions...
 Downloading artifact: Rmath
    Downloading [>                                        ]  0.0 %

It hangs and never stop.

I setted up my .curlrc so that curl works correctly under my proxy:

julia> run(`curl https://google.com`)
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
<A HREF="https://www.google.com/">here</A>.
</BODY></HTML>
Process(`curl https://google.com`, ProcessExited(0))

julia>

Standard git operations also works correctly, since the General registry can be removed, reinstalled, updated, etc… I can install artifact-less packages without any issue.

Thinking Pkg was using Powershell to download the artifacts, I tried this solution but it did not work, it still hangs on artifacts.

Base.download("https://google.com") has the same hanging issue. By looking around, upon forcing some environment variables that matches my .curlrc before launching julia by:

export BINARYPROVIDER_DOWNLOAD_ENGINE="curl --proxy <my_proxy> --ssl-no-revoke --insecure"

I am able to make Base.download work, but not for https:

julia> Base.download("google.com")
"C:\\Users\\XXX\\AppData\\Local\\Temp\\jl_D511.tmp"

julia> Base.download("https://google.com")
ERROR: HTTP/1.0 200 Connection established (schannel: next InitializeSecurityContext failed: Unknown error (0x80092012)) while requesting https://google.com

 [Very long stacktrace, the same one.]

Moreover, I tried DebugArtifacts and the same thing occurs:

julia> using DebugArtifacts

julia> debug_artifact("OpenSpecFun")

But with a simple run of curl, everything is still OK.

julia> run(`curl https://google.com`)

How can i tell the libcurl that is inside julia to respond to my .curlrc ?
Can i pass directly some parameters (the same i passed in my .curlrc to Julia’s libcurl ? How ?
