Hi there, I have connected DYNU with my IPS in order to enable Dynamic DNS. The problem is that when I connect to the server with an SFTP client, FileZilla, I am not able to connect using the hostname, which resolves in the IPv6 address provided by your service.
On the other side, when I connect FileZilla using the IP address, it works fine.
