Hello,

Could you let us know what's configured for "TLS Encryption Support" in "WHM >> FTP Server Configuration"? Also, are you able to reproduce the issue with additional accounts in FTP clients such as Filezilla?

Thank you.

Hello Michael,

TLS Encryption is set to "Required ( Command/Data)".

>>> Also, are you able to reproduce the issue with additional accounts in FTP clients such as Filezilla?
We have disabled plain text login, so main cPanel user only has the ftp access.

Hello,

I've seen cases where this happens because the passive port range for FTP is blocked by a firewall rule. Could you review our Passive FTP document and let us know the issue continues? Also, please try using a different FTP client to verify the issue isn't isolated to that custom script.

Thank you.
