Server did not properly shut down TLS connection (General questions)

Hi there-

I'm getting this error with version 3.2.0.360. I just updated to that version to try to get rid of the issue in case it was due to an out-of-date SFTPServer component version.

I saw this forum post with the same error which may be relevant, with ProFTPD:

Please let me know the situation and what to do to eliminate this error, thanks!
