Starting March, 2020, with 2019 release wave 2, Business Central only supports Transport Layer Security (TLS) version 1.2 or later. Upgrade to one of the latest supported Business Central release waves to remove support for earlier versions of TLS. If your solution or an add-on uses TLS 1.0 or 1.1, you must update that configuration or add-on to TLS 1.2 or later as soon as possible.
