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. However, in April, to avoid disrupting customers in the midst of the COVID-19 pandemic, we announced that we would continue to support TLS 1.0/1.1 until further notice.

Now that some time has passed, we feel it is important to resume our plans to help ensure our customer’s security. As such, NuGet.org will permanently remove support for TLS 1.0 and 1.1 on June 15th, 2020. Prior to that date, please ensure that your systems use TLS 1.2.
