I am behind a large-corp firewall, and following [this advice](https://discourse.julialang.org/t/artifact-hash-mismatch-when-installing-libpng-julia-1-6-1/61766/26) I am trying JuliaHub. I made an account, downloaded the auth token:
```julia
PS C:\Users\Cedric> dir .julia/servers/juliahub.com/auth.toml
C:\Users\Cedric\.julia\servers\juliahub.com
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 2023/06/02 9:58 2097 auth.toml
```
but somehow this isn’t enough
```julia
julia> ENV["JULIA_PKG_SERVER"] = "https://pkg.juliahub.com"
"https://pkg.juliahub.com"
(@v1.9) pkg> add ScikitLearnBase

Am I doing anything wrong?

My first guess is that you might have to change `.julia/servers/juliahub.com/auth.toml` to `.julia/servers/pkg.juliahub.com/auth.toml`.
But, in general, instead of managing the `auth.toml` files manually, I prefer to just use PkgAuthentication.jl:
> **[GitHub - JuliaComputing/PkgAuthentication.jl](https://github.com/JuliaComputing/PkgAuthentication.jl)**
>
> Contribute to JuliaComputing/PkgAuthentication.jl development by creating an account on GitHub.

That worked! Thank you. Unfortunately, I get the same hash mismatch problem installing artifacts as I did before on Julia’s default servers…
```julia
(@v1.9) pkg> add GR

```
Somehow the firewall gets in the way, and delivers some kind of “This page is forbidden” HTML page instead of delivering the actual file, hence the hash mismatch.

I’ve tried downloading this same file from both `juliahub.com` and `pkg.juliahub.com` (both should work) using `Downloads.download` with the appropriate auth headers manually added and it works for me:
```julia
julia> using Downloads, Tar
julia> token = "secret auth token from ~/.julia/servers/juliahub.com/auth.toml";
julia> tmp = Downloads.download("https://juliahub.com/artifact/9dbefe9cacd3199aed3c251e7ecbccc93ca86d2f", headers=["Authorization" => "Bearer $token", "Julia-Version" => "1.9.1"])
"/var/folders/fm/ld6yc24s56q94q3n2wf20v7m0000gn/T/jl_yh0tA9CHUL"
julia> Tar.tree_hash(`gzcat $tmp`)
"9dbefe9cacd3199aed3c251e7ecbccc93ca86d2f"
```
You could try the same with your auth token value. You might need to refresh it, which the Pkg logic takes care of automatically. That could at least allow debugging what content you’re getting that doesn’t look like a valid tarball.
I’m also not sure why the second download would be failing since I’ve downloaded that binary from GitHub and gotten the correct SHA256 hash. But it shouldn’t even be getting to that point since the first download from JuliaHub should work.

Hi Stefan, thank you for looking into it. We found a way to temporarily bypass the firewall, and all is good for now. Julia has entered big-corp 🙂
