I am using Director 4.7.0
I have been getting intermittent errors on connecting to SFTP server:
I am able to recover on the next run, but it is annoying. Is there any fix for it?

You can look at modifying your retries and retry intervals. Also, look at your time out value. You could possibly increase that value as well.
