We are able to download but cannot upload anything

I have encountered a problem that is unable to see a specific directory in the equipment which OS is VxWorks version 5.4. I have tried with some equipment, but result is same.

The phenomenon is as follows ;

1. Use of FileZilla Client for Windows version 3.0.4.1.

   Result : I am able to see a specific directory. Specific directory is ‘aaaa’ and ‘bbbb’.

2. Use of FileZilla Client for Windows version 3.2.8.1.

   Result : I am unable to see a specific directory. Specific directory is ‘aaaa’ and ‘bbbb’. ‘Response: 501 Directory non existent or syntax error’ occurred.

3. Use of FileZilla Client for Windows version 3.3.0. (latest version)

   Result : I am unable to see a specific directory. Specific directory is ‘aaaa’ and ‘bbbb’. ‘Response: 501 Directory non existent or syntax error’ occurred.

I have attached ‘comparative table of packet capture data using WireShark’ and ‘comparative table of Log data using FileZilla’ for your reference.

Please let me know if I have to apply the patch file for FileZilla Client software (Version 3.3.0) or any other settings.
