It basically means that the server is unable to ensure that the login details are correct. Here we\u2019ll see why this error occur and how it can be settled.<\/span><\/p>\n<h3><span style=\"color: #000000;\">1. Incorrect login details:<\/span><\/h3>\n<p><span style=\"color: #000000;\">sometimes FTP users get confused about the format of the username or can use the wrong password.<\/span><\/p>\n<p><span style=\"color: #000000;\">Regular situations are :<\/span><\/p>\n<ul>\n<li><span style=\"color: #000000;\">\u00a0FTP users not using the domain name at the end of the <a href=\"https:\/\/cpanelplesk.com\/wp62\/how-to-ftp-from-command-line\/\">FTP<\/a> user . Eg., using \u201cftpname\u201d instead of \u201cftpname@domain.com\u201d.<\/span><\/li>\n<li><span style=\"color: #000000;\">\u00a0FTP users including a space either in front or at the end of the password when they copy-paste it.<\/span><br \/>\n<span style=\"color: #000000;\"> Such situations usually occur with new hosting accounts, or with those accounts which recently modified their passwords.<\/span><\/li>\n<\/ul>\n<h3><span style=\"color: #000000;\">2.

To eliminate the problem, Please follow:<\/span><\/p>\n<ul>\n<li><span style=\"color: #000000;\">Synchronize the security passwords by going to WHM &gt;&gt; cPanel &gt;&gt; \u201cSynchronize FTP Passwords\u201d<\/span><\/li>\n<li><span style=\"color: #000000;\">Change FTP from Pure-ftpd to Proftpd in WHM &gt; \u201cFTP Configuration\u201d and switch back to Pure-Ftpd.
