When performing a “Test” to an upstream registry, you may receive the following error as shown in the image below:
The "Test" simply sends a HEAD request to the endpoint. Some endpoints will return a 404 response to the HEAD request indicating that the upstream is not browsable.
(Please note, NuGet, Docker, VCS and CocoaPods repositories don’t send a head request. By default the connection will succeed.)
