I have two machines, my dev machine and the build server. For the latter nuget restore does try to pull a wrong version for a particular package
16:15:48 Failed to retrieve information about 'Autofac' from remote source 'https://nuget.intra/api/nuget/virtual-nuget/FindPackagesById()?id='Autofac'&semVerLevel=2.0.0'.
I've checked the complete solution and there is no rederence to version 2.0.0 but only 4.x.x. More strangely the nuget restore works fine on my dev machien

Both have the same nuget version installed with choco install nuget.commandline. I also distribute the same Nuget.Config to both machines.
Update
Further up in the log I can see the following
Unable to load the service index for source https://nuget.intra/api/nuget/virtual-nuget.
07:43:45 Invalid length for a Base-64 char array or string.
Maybe due to the fact that the index cannot be read the wrong version is downloaded? However, still doesn't explain why on my dev machine all works fine.
Update 2
So there is a Visual Studio 2017 installed on the build server. I've checked various other sources and tried some things, without success.
- Nuget connection attempt failed “Unable to load the service index for source”
- Package Manager Error: Unable to load the service index for source (bad proxy settings)#
Checked various files for proxy settings but none of them has one, which is good
