Problem with lftp solved

I thought I’d share this little solution with people as its been bugging me for ages. My command line ftp client of choice, lftp, recently started not connecting. I couldn’t find a suitable solution until I noticed that the AUTH command was being used when I normally don’t make use of that for ordinary ftp sessions.
I added the following line to my lftp.conf file:

set ftp:ssl-allow false

This fixed the issue of failing to connect and everything is now working as it should. Hope this helps someone who is in a similar fix.
