In June 2021 we will remove support for TLS 1.0 and 1.1 from our private NuGet feed and remove non-HTTPS endpoint that serves Hangfire Pro and Ace packages. The same steps happened with the official NuGet Gallery (where the most packages for .NET are stored) in April, 2020 so it’s highly likely your NuGet client already supports TLS 1.2 or higher and you don’t need to upgrade it. To support all the latest features and have the fastest install/update experience, please ensure you are using the following NuGet V3 API endpoints (V2 will still be supported):
NuGet V3 feed for Hangfire Pro:
NuGet V3 feed for Hangfire Ace:
