Can't connect FTP on ATT Uverse

Hi,

I'm on ATT Uverse at home, and I can't connect to FTP using the third party FTP app. Images on my websites don't load.

However, when I visit the websites on my cellphone (Sprint), it works fine.

Also, I'm on Comcast at work, and FTP, website, images, everything work, too.

I called ATT, but they couldn't help.

Any ideas would be highly appreciated.

Please run the networking test and post here the results.
Other AT&T customers reported networking problems, so it's very likely that also your problem is caused by your ISP.
