BTW a local clone via Git works. So I guess it’s not an networking issue.

```julia
PS C:\Users\a97812\GitHub> git clone https://github.com/JuliaDiff/DiffRules.jl.git
Cloning into 'DiffRules.jl'...
remote: Enumerating objects: 376, done.
remote: Total 376 (delta 0), reused 0 (delta 0), pack-reused 376
Receiving objects: 100% (376/376), 65.68 KiB | 1.82 MiB/s, done.
Resolving deltas: 100% (212/212), done.

```

So I tried to install that way in julia - with an other error

```julia
(v1.0) pkg> add https://github.com/JuliaDiff/DiffRules.jl.git
   Cloning git-repo `https://github.com/JuliaDiff/DiffRules.jl.git`
ERROR: failed to clone from https://github.com/JuliaDiff/DiffRules.jl.git, error: GitError(Code:ERRO
R, Class:OS, failed to set credentials: Falscher Parameter.
)

```

_(Falscher Parameter means wrong parameter)_

So I tried to install from local file clone above - and I suceeded

```julia
