Hi all,
I have both IPv4 and IPv6 enabled on my server. For one of the websites a created an FTP account but I have trouble setting up a connection over IPv6.
Of cours I have added an access rule for the passive ports as mentioned in the docs but I still cannot connect via IPv6. In FileZilla I get the message "Connection refused by server". Via IPv4 everything works fine. See the two below logs:

In UFW the passive rules are listed for both IPv4 and IPv6 but even if I temporary disable UFW I still cannot connect.
Did anyone encountered a similar issue? And if so, how did you solve it?
If we only can connect via IPv4 that is also fine but then each domain should have, by default, a single A record 'ftp' pointing to the server otherwise it will only work for customers/networks which are not IPv6.
