lftp Fatal error: Certificate verification: Not trusted

When i connect to an FTP server, i get following error

root@hestia-lnx:~# lftp -u sokftp 54.37.215.1
Password: 
lftp [email protected]:~> dir

To fix this, run

set ssl:verify-certificate no

You can add this to /etc/lftp.conf to make this permanant

vi  /etc/lftp.conf

Add

set ssl:verify-certificate no
