Error: An established connection was aborted by the software in your host machine.

I'm new to FTP and am having to transfer files for a new job. I cannot  seem to get this to work. I've done everything I can (firewalls and such) based on what I've been able to find and read online and I haven't been able to resolve the problem. Can someone help, please? 

 

You need the correct host and protocol. Then open a new connection: menu: File - Connection
