FileZilla 9.0.44 421 Login time Exceeded


After upgrading to 9.0.44 beta, a FTP client with ssl will issue “AUTH TLS”

Expected: Filezilla Server should response with “234 Using authentication type TLS” within a second or two.

Actual:  The problem occurs every other connection attempt or 3+ consecutive times.  The point is that sometimes it responds to AUTH TLS fast, sometimes slow, sometimes timed out, triggering “421 Login time exceeded. closing control connection” error.


Go to “services” and restart Filezilla.  FTP connection speed should be normal again.
