GnuTLS error -53: Error in the push function

[mic.potenza]

I'm using FileZilla Server 0.9.34 on Windows 2003 SBS and FileZilla 3.3.1 on Windows Vista Business SP2
when using FTPS to connect to my server I always get an error, please, see my log below.
Any idea?
Regards

Looks like there's a router and/or firewall that's interrupting the connection.

Please read the Network Configuration guide.

problem solved, thanks.
It was a NAT problem

[marcusfive]

also i have the same error:
"GnuTLS error -53: Error in the push function"

i have a techus nat, and i have set ftps esplicit

how can solve?
nas is connected to a switch and then to a modem of alice.
i have also set in alice modem the virtual server in port 21 with TCP protocoll

thank you

i have also set in alice modem the virtual server in port 21 with TCP protocoll

That's not a modem, but a modem-router. Please read Network Configuration.

i have solve by:
-on server i tur off the secure mode esplicit, now the connection ora not encrypt, and on ftp client i have set the normal connection
-on ftp client i have set active mode.

now work
bu i would to turn on the encrypt mode.
if i do, there are the same error: "GnuTLS error -53: Error in the push function"
this is the posiction of server:
modem/router telecom -> switch -> server ftp

thank you

[boco]

The forwarded port 21 is not enough. The Network Configuration guide tells you all about the Passive port range.

[marcusfive]

ok i will try

[mikeloeven]

i am having this issue two but it only happens when i try to connect to my ftp server from work. i changed the server to use ports that i know are open on the corperate network but it changed from activly refused to push function error. so i am a bit lost for all intents and purposes it should work. and since i have no access to the corperate network it is hard for me to figure this out

[boco]

I'd suspect a corporate firewall (such as ISA firewall) is interfering.

I have been looking for a solution to this problem too for a long time. In my FTP server config I had entered a wrong masquerading IP address. Once I fixed the masquerading IP address, my connections worked perfectly. So this is not always being caused by some kind of firewall/router/modem, but can also be caused by a misconfigured FTP server config. Anyways, this seems to be a basic networking issue since the masquerading IP address is needed to be able to allow FTP clients on the external side of a NAT'ed network to connect to the FTP server (as I am understanding it).

When connecting using standard FTP, connection is fine.
When I attempt to use FTP - Require explicit FTP over TLS I get this same error, like so:

If I attempt to use SFTP I get a timeout error everytime...

and if I try FTP - Require implicit FTP over TLS:

Status:	Connection attempt failed with "ECONNREFUSED - Connection refused by server".
Error:	Could not connect to server
Status:	Waiting to retry...
Status:	Connecting to XXX.XXX.X.XXX:990...
Status:	Connection attempt failed with "ECONNREFUSED - Connection refused by server".
Error:	Could not connect to server

I have tried changing firewall settings, port forwarding, etc, with NO luck.

I would really like to have a secure FTP set up one way or another, any ideas on why this is happening???
Thx

Sorry- Disregard previous post, I got it working. Uninstall and re-install of FileZilla worked!

[brhend]

Encountered the same issue.

Solution was different. Simply changed encryption

Site manager > select "my Site" > General Tab > encryption

select "Use plain FTP"

[boco]

Quite not a solution to lower all your defenses instead of dealing with the problem, eh?
