Schannel is a Security Support Provider (SSP) that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) Internet standard authentication protocols. The Security Support Provider Interface (SSPI) is an API used by Windows systems to perform security-related functions including authentication.

What is the cause? This may happen because the TLS encryption is not enabled on your server. It may cause an issue connecting applications via HTTPS, and TLS encryption fails on the connections.

How to check if TLS 1.2 is enabled? If the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\DisabledByDefault is present, the value should be 0.

TLS 1.2 is enabled by default at the operating system level. Once you ensure that the .NET registry values are set to enable TLS 1.2 and verify the environment is properly utilizing TLS 1.2 on the network, you may want to edit the SChannel\Protocols registry key to disable the older, less secure protocols.

It means communication with the server was attempted using a recognized but unsupported TLS version. If your server is set to accept only communications using TLS 1.2 or newer, for example, then anything that tries to communicate via TLS 1.1 or lower will throw this error.
