Error When Starting Up SSH session -13 11

[JEBG1234]

when i try to connect to my ftp server on port 21 using the correct password and username and host i press mount after filling out the info and like 20 or 15 minutes later i get the error "Error when starting up SSH session -13 11" do i have to fill out the root because i dont know exactly where it is on the server so do i need to know that or do i need some other software or application for chromebook to make it work im on Chromebook Acer C720.

I am getting the same error and I am on a LG Chromebase.

Got the same error, I am guessing that my ftp server configuration is currently not supported and thus the error.

Still having this problem. Does the SFTP client not support standard FTP?
