There may be more than one problem, but notice this in the error message you posted:

The group repository nuget-group contains a proxy with different nuget version

You can’t mix v2 and v3 proxies in the same group, they speak different protocols. See the note at the top of the page, here:

There is a problem with the configuration of your Nexus Repository instance. If you’re not the administrator, you will need to contact your administrator.
