Re: An existing connection was forcibly closed by (General questions)
Tamil,
Did you load a certificate in Core FTP Server?
FTPS protocol as to have one defined in order to work. Otherwise connection would be refused, since connection can't be secured.
I duplicated the The handshake failed due to an unexpected packet format with no Certificate loaded. As soon as I set Self-signed certificate, everything started working properly.
