Description

Hi,

We are currently experiencing an issue with the latest version of the client (3.11.0(x64)) where it is unable to open the data connection after entering passive mode and entering MLSD.

This is however is only the case (as far as we have seen) on Windows 7 x64 Professional as the connection works as expected on Windows 8.1 x64.

We have a number of logs, one from the Windows 7 x64 machine, one from the Windows 8.1 x64 machine and one from ftptest.net.

Here is the detailed connection log from the Windows 7 x64 machine:

As can be seen it connects fine on Win 8.1 and 'ftptest.net' however is having issues on the Windows 7 x64 machine. These issues are not present however in earlier versions of FileZilla (versions 3.2.7 and 3.9.0.6 to be precise).
