How to enable explicit FTP over TLS login?

Hi,

I am not seeing any issues with AUTH TLS in my test server:

Code:

# openssl s_client -starttls ftp -connect 127.0.0.1:21 -quiet
depth=0 CN = ***REDACTED***, emailAddress = ***REDACTED***
verify error:num=18:self signed certificate
verify return:1
depth=0 CN = ***REDACTED***, emailAddress = ***REDACTED***
verify return:1
220 You will be disconnected after 15 minutes of inactivity.
user $username
331 User $username OK. Password required
pass $password
230 OK. Current restricted directory is /

I suspect there is an issue with the cipher suite. Have you made any customizations at WHM > Service Configuration > FTP Server Configuration? Perhaps you could also enable debugging in your FTP client for more details?

Thanks,
