FTP error cannot access

I installed the latest version hestiacp and failed to access FTP via port 21.

>>>  PASV
<<<  500 OOPS: invalid pasv_address

Did you check whether range of TCP ports 12000-12100 are open in Hestia AND in the firewall used by your hosting provider (if it provides one)?

If the range of ports is open in both, Hestia and your provider and you can’t connect, add this directive pasv_addr_resolve=YES to /etc/vsftpd.conf file and once done, restart the service systemctl restart vsftpd and try again.
