Ssl_connect:error in sslv2/v3 read server Hello A

I would like with Keepass 2.20.1 and its plugin Ioprotocoleext 1.6 to connect to my database via FTPS.
Normally it uses the port 990 but for firewall security reasons, I has to use port 22.
On port 990 It perfectly works, but for the port it's not the same

Here is the WINSCP Error message:

Ssl_connect:error in sslv2/v3 read server Hello A
Can ' t establish SSL connection
Disconnected from server
Connection failed.

I tested with success with Filezilla.

The FTPS is a IIS 7.5 running on a server R2
The certificate is a self signed one.

Workaround:

It looks like you is using Explicit TLS with Filezilla and while implicit SSL/TLS with WinSCP.

Try using Explicit TLS with WinSCP too.
