I attempted to do a `]update` on a private julia repo and got the following error:

```julia
(mypackage) pkg> update
   Updating registry at `~/.julia/registries/General`
   Updating git-repo `https://github.com/JuliaRegistries/General.git`
   Updating git-repo `https://git.mycompany.com/mypackage.jl.git`
Username for 'https://git.mycompany.com': socksNsandals
Password for 'https://socksNsandals@git.mycompany.com': 
ERROR: failed to fetch from https://git.mycompany.com/mypackage.jl.git, error: GitError(Code:ERROR, Class:Net, remote requested authentication but did not negotiate mechanisms)

```

This recently was working form me in julia 1.1, but I simultaneously  
a) upgraded to julia 1.4.2  
b) upgraded my mac OS from High Sierra to Catalina  
c) enabled two-factor authentication for my gitlab account

Outside of julia, I am able to push/pull, so this seems to be a julia-specific issue.
