FTPS - slow initial connection

.NET Framework 4.8 We are facing a performance problem - Why is it significantly slow (around 1 minute) first time for TLS authentication. Second time onwards TLS authentication is fast. When there is gap in communication of some hours (no connection/communication) with the FTP server, then again the significantly slowness is observed for TLS authentication Note this is FTPS QUESTIONS: How do I control this timeout? Is there any tracing to see this flow? How do I enable it? What is reasonable time it should take to validate certificate chains?
