I just installed ISPConfig 188.8.131.52 on Debian 7 and no user can connect via SFTP. Shell users (all Jailed) are correct because they can connect via SSH. Using FileZilla SFTP I get: Connection closed by server with exut code 1 Using Bitvise Tunnelier SFTP I get: Opening new SFTP session Closing SFTP session. Using Bitvise Tunnelier SSH I can connect normally. Thanks for any help.
