I feel like there's a lack of information. Make sure that not only are your username and password are correct, but that the server's IP and port are also correct. I feel like the port number would be your stumbling block.

Thanks, I double checked my password and even tried with both port 21 and 22 and still the same...

Hi Jose,

Make sure you're connecting to port 21 as a TLS request requires an SSL certificate to be installed for the FTP service which it isn't for your server, the different is port 21 runs on a standard socket whereas port 22 which is what I assume you're attempting to connect to runs through an encrypted connection.

Hope that helps.

Hi! thanks for the answer, unfortunately I just tried with port 21 and 22, still the same...

Which version of Filezilla are you running? I recently had problems connecting to some of my (non wordpress) sites after an upgrade to version 10. Once I'd downgraded it was fine again. :-)

I was using the last one for pc (since i'm still on OSX 10.6 the mac version won't work, so I downloaded the PC version which I use in Windows 7 in Parallels) and I'm using wordpress. Still doesn't work. Which version you suggest? do you have a link please?

I had the same issue trying to connect to my Godaddy server for my wordpress sites a month or so ago.

After calling Godaddy, they recommended version

A quick Google Search "filezilla mac" bring multiple results!

Good luck!

Hey! Thanks for the reply, unfortunately I'm still ond 10.6 OSX and the is only supported on 10.7 or higher...


I recommend upgrading to 10.7 or higher.

My lady upgraded and there really isn't much difference.

Good luck!
