Unable to connect to server?

I am having a difficult time getting the site to the server using Filezilla. I have used everything correctly in the file panel for host, username, password and port number and it still says Error: Connection timed out after 20 seconds of inactivity. Error:Could not connect to server. Is there something extra I need to do to get this to work? Any help would be greatly appreciated.

Check the parameters here.

Can you execute this test?
Can you try with a different connection?

Bye!
