If you are still having problems, the issue may be with your server. VFSLogFilePatternReceiver uses Jakarta Commons VFS, which uses the JSch library to support the 'sftp' protocol. According to their website, this is: *SSH File Transfer Protocol(version 0, 1, 2, 3)
*I'd suggest verifying your server actually supports SFTP. It may support ssh connections but not support the SSH File Transfer Protocol.
