Can not connect FTP on CentOS 6.8 7.2 x64

I wouldn't publicly post your login info ! make sure to change username and password ASAP

• Did you let the script generate a password for you or set your own ?
• Did you make sure to enable explicit TLS/SSL mode and enable PASV passive mode like in 1st post here.
• Which FTP client ? As not all FTP clients support FTP explicit TLS/SSL mode only clients listed at bottom of this post.

From 1st post here, try the pure-pw commands to display pure-ftpd user details and change the user password. Also pure-pw manual is here and http://download.pureftpd.org/pub/pure-ftpd/doc/README.Virtual-Users

list all pure-ftpd created virtual FTP users

Code (Text):

pure-pw list

Code (Text):

pure-pw list

ftpuser3 /usr/local/nginx/html/./
ftpuser4 /home/nginx/domains/domain1.com/./
ftpuser6 /home/nginx/domains/sub.domain1.com/./
ftpuser5 /home/nginx/domains/domain2.com/./

to delete virtual FTP user

Code (Text):

pure-pw userdel FTPUSERNAME
pure-pw mkdb

change virtual FTP user's password

Code (Text):

pure-pw passwd FTPUSERNAME
pure-pw mkdb

also check if your ip you connect from has been banned via

Code (Text):

csf -g IPADDRESS

whitelist ip if you haven't already

Code (Text):

csf -a IPADDRESS

also check your pure-ftpd logged messages in /var/log/messages

Code (Text):

awk '/pure-ftpd:/' /var/log/messages
