Cannot connect to FTP using explicit FTP over TLS

I try to connect to a FTP folder with the following specifications:
WinSCP Version 5.16.2 RC (Build 10017)
Windows Server 2016 Standard. Version 1607
FTP, using explicit FTP over TLS and port 990
GUI, commander interface

It fails directly and I get the following error message:
"TLS connect: error in error
Can't establish TLS connection
Disconnected from server
Connection failed."

It worked with FileZilla version 3.46.3.
Description: WinSCP logs
Description: Log file from FileZilla

Cannot connect to FTP using explicit FTP over TLS

Hello, I was able to connect. The error comes from the fact than when I select explicit it reset the port 990 I put. And when I put port 990, the encryption changes to Implicit.

And that's correct. Port 990 is for implicit TLS/SSL. Explicit TLS/SSL uses port 21. If your server is configured to use explicit TLS and port 990, it's misconfigured.

Thanks for your answer Martin. So the configuration I received is wrong.
