Error: Failed to retrieve directory listing when connecting to Globalscape SFTP server Version 3.3.0

[twgower]

Directory listing fails when connecting to Globalscape’s SFTP server v 3.3.0 other sftp clients work fine with same account. Contacted Globalscape support and was informed that their application is functioning as designed and that the problem needs to be resolved by Filezilla. Upon further investigation I discovered that this problem started with Filezilla version 3.1.0, versions 3.0.9.3 and before work fine.

See Filezilla debug log below.

You are using a broken server that is violating the TLS specifications by not sending a closure alert at the end of the transfer.

You have to upgrade to a proper server.
