This has also happened on earlier versions.
Filezilla gives the message "Failed to retrieve directory listing" during connect. I can get around this by accessing my Cable Modem's Administrator function and changing my Firewall setting to "Minimum". I have to keep it at this level during the entire FileZilla session, through and including Disconnect.
Naturally, I do not appreciate having to leave myself vulnerable, even for a relatively short window. I'd prefer to keep the higher level set at all times.
The log, in its entirety, [minus the particulars of my site] reads:
Status: Resolving address of [XXXXXXXXXX.XXX] Status: Connecting to [YY.YY.YY.YY]:21... Status: Connection established, waiting for welcome message... Status: Initializing TLS... Status: Verifying certificate... Status: TLS connection established. Status: Connected 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 ([YY,YY,YY,YY],197,52) Command: MLSD Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing Status: Disconnected from server
... and it repeats once, except the second time, one line is different:
Command: PASV Response: 227 Entering Passive Mode ([YY,YY,YY,YY],197,46)
This is the only web-site to which I connect.
I do not know if this is a function of FileZilla in general, of my site in particular, or of my Site Manager configuration.
As to the latter, I do not have a Port specified. I don't know if the ":21..." refers to the default port, or what the ",197,52" or "197,46" means.
I would like to know if:
(a) Specifying a particular Port number will clear up this problem. (And, if so, what port number?)
(b) This is a "Bug" or a Feature",
(c) If the former, can it be fixed?
