Just as the title says. Dreamweaver FTPs fine. Filezilla does not.

I can connect to our other servers fine, just one serer won't work.
It just isn't my computer either. Other computers have the same issue, whether they're Windows or OSX.

It simply says....

Status: Connection established, waiting for welcome message...
Status: Initializing TLS...
Status: Verifying certificate...
Status: TLS connection established.
Status: Logged in
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is your current location
Command: TYPE I
Response: 200 TYPE is now 8-bit binary
Command: PASV
Response: 227 Entering Passive Mode (104,36,149,174,252,86)
Command: MLSD
Error: Connection timed out after 20 seconds of inactivity
Error: Failed to retrieve directory listing
Status: Disconnected from server
It will repeat this over and over.

Thoughts?
