Currently, the LaunchDarkly dashboard (app.launchdarkly.com) requires TLS 1.2, but the events and streaming API allow TLS versions 1.0, 1.1, and 1.2.
Starting August 31, 2021, we will be disabling TLS 1.0 and TLS 1.1, and requiring TLS 1.2 or greater, for the following LaunchDarkly endpoints:
Our analysis indicates this change would primarily affect applications using the LaunchDarkly .NET SDK in legacy environments. On August 3, we sent an email to LaunchDarkly account owners and admins associated with projects we have observed making TLS 1.0/1.1 requests to our service. If you have not received a separate email notification, your application is already making requests using TLS 1.2 and will not be affected by this change.
Please feel free to contact LaunchDarkly Support with any questions or concerns.
