SFTP not working on Ubuntu16.04

Hi all,

I can start a sftp server using girder sftpd. However, I cannot connect to it using FileZilla or psftp.
We tested it in ArchLinux and Mac and everything worked.

Here is the output log of FileZilla on Ubuntu

|Status:|Connecting to localhost:8022...|
|Status:|Connected to localhost|
|Status:|Retrieving directory listing...|
|Status:|Directory listing of "/" successful|
|Status:|Retrieving directory listing of "/(unknown date) b'collection'"...|
|Command:|cd "/(unknown date) b'collection'"|
|Error:|Directory /(unknown date) b'collection': received failure with description 'Failure'|
|Error:|Failed to retrieve directory listing|
|Status:|Retrieving directory listing of "/(unknown date) b'user'"...|
|Command:|cd "/(unknown date) b'user'"|
|Error:|Directory /(unknown date) b'user': received failure with description 'Failure'|
|Error:|Failed to retrieve directory listing|

Thanks for your help,

Actually, it was not working with an old version of FileZilla (v-3.21).
An upgrade to the last version (v-3.41) fixes this issue.
