NuGet.org will permanently remove support for TLS 1.0 and 1.1 on June 15th
Last November, we shared our two-stage plan for deprecating TLS 1.0/1.1 on NuGet.org in which we stated that the permanent removal of TLS 1.0/1.1 support would occur in April 2020.

Once you have an inner-loop experience there is then a, sometime...
