- You are using a custom NuGet feed
- when running nuget.exe you receive the following error message:
Response: Invalid URI: The hostname could not be parsed.
Double-check the URL you are using (for example, try opening it on a browser). Typically, the URL should end with /nuget (for some servers like ProGet with /nuget/<feedname>).
