Description

Just want to report issue with Remote FTP having issue with TLS v1.2. Also wanted to know how to check TLS version? Is there a way to force it to TLS v1.2, I have check the java controller its been set already to TLS v1.2 but I am not sure if netbeans uses different one.

Issue occur when shared hosting have upgraded their server to TLS v1.2 ftp will close without indication.
