After successful connection using lftp

lftp -u username,userpass target_ip

a simple command like ls is not working but hanging and wait for timeout. The reason can be a destination target self signed certificate or, more possible, a destination misconfiguration regardint ftp ssl. To avoid it, run it without ssl:

lftp -u username,userpass target_ip
lftp> set ftp:ssl-allow no

or one liner:

lftp -u username,userpass target_ip -e "set ftp:ssl-allow no;"
