lftp returns error : "Cannot assign requested address"

[Mausy5043]

Trying to use lftp to upload data to my webserver is unsuccesful:

$ lftp -d mysite.nl
lftp ftpuser@mysite.nl@mysite.nl:~> ls
---- Connecting to mysite.nl (xxxx:xxxx:x::xx) port 21
**** connect(control_sock): Cannot assign requested address
---- Closing control socket
ls: Cannot assign requested address
lftp ftpuser@mysite.nl@mysite.nl:~> ls
---- Connecting to mysite.nl (xxxx:xxxx:x::xx) port 21
**** connect(control_sock): Cannot assign requested address
---- Closing control socket
ls: Cannot assign requested address
lftp ftpuser@mysite.nl@mysite.nl:~> exit

Using the same settings and commands on another Debian machine (Ubuntu 16.04) is succesfull.
I expect a package is missing but haven't been able to figure out which one.
The problem has persisted for the past couple of months.
Using a build of the current (07OCT2017) v1.1.x branch still doesn't fix the problem.

Is lftp IPv6-aware? It may not be, and it might be trying to use an IPv4 socket with an IPv6 address (the address you masked out looks like an IPv6 format).

[Mausy5043]

Yes it's an IPv6 address.
How can I determine if that is what's happening?

Same issue here, with a demain name that resolves as a IPV4 adress. Working well on another Debian computer.
Solved using IP adress instead of domain name.

[Mausy5043]

Finally seem to have solved it.

Adding this line to ~/.lftprc :

set dns:order "inet inet6"

seems to work.

If someone could confirm this?

@Mausy5043 this isn't really related to the installer

closing for now
