Hourglass stays on when trying to reach www

I want to access my folders and everything has worked fine for a long time now.
All of a sudden, I get an hourglass when I click on the plus sign next to my web address and it won't go off no matter what.
I want to create a new folder in the www section as always and drag and drop my HTML files into it as usual.
Any suggestions?

Please install the latest version from
https://www.smartftp.com/download

Then go to the menu: File->New Remote Browser and enter all the information and click OK to connect.

Regards,
Mat
