Datasnap TDSRestConnection error sending data 12175

[Tuan 0]

Hello

 

When update to windows server 2020, my client TDSRestConnection can not Generate DataSnap client class. It show "error sending data : (12175) A security error occured"

 

My app can run because i have added in code:

DSRestConnection1.SecureProtocols := [THTTPSecureProtocol.SSL3,THTTPSecureProtocol.TLS1,THTTPSecureProtocol.TLS11,THTTPSecureProtocol.TLS12];

but on DSRestConnection1 properties don't have SecureProtocols properties.

 

Thank you very much.
