What i had to do was modify how launchpad handles ftp a bit. The normal launchpad used code that should work, but after some research I found 1and1 has strange way for receiving ftp requests. It’s why i could use WinSCP to connect to 1and1 but not launchpad, as WinSCP is a bit more fleshed out for ftp handling(as it should be). Would you want me to create a pull request with the extra code I added?
