If your login to FTP is failing, please make sure your username is correct. Most common error you would see is "530 Authentication failed".
For FTP, the username should be egnyte_username$domain where egnyte_username is the username you use for the Egnyte account and domain is your Egnyte account at https://domain.egnyte.com
For example, if you access Egnyte at https://abc.egnyte.com and you use username jim to login, then for FTP the username should be jim$abc.
If all this is correct and you still can't login, please contact us by logging a ticket.
Note: FTP is available to Office and Enterprise Plans. In addition, FTP is only available to Admins and Power Users.
