I have just setup a FTP server on my linux based server to allow editing of configs remotely. I tested it first using the Filezilla FTP client, and I was fully able to connect and view my files. However, upon trying to connect through chorus, it locks up, and gives this error as output in the terminal I am running in:

Both server for FTP and client are running ArchLinux, and as mentioned I verified FTP server setup with Filezilla, to confirm it is not a issue with the FTP server.
