Getting an error during install that it cannot add package isoband. Looks like connection issues but it downloaded the prior packages just fine. Running on M1 Mac.

```julia
pkg> add GLMakie

When I hit the URL in my browser it downloads just fine.

Is there a proxy involved?

Got this fixed. Somehow the .CondaPkgs folder that PyCall installs was causing this.
