username: Novocaina (case sensative so first n will be capital)
Host : ftp.marketplace.envato.com
Please note: If you use the https://author.envato.com/upload (stock video/motion graphics) the Host will be ftp.author.envato.com
You need to create a Personal Token here: https://build.envato.com/create-token/
Use this token as your password in FTP.
Hope this will help.
