Depending on the hosting provider you are using, the path may be different.
Did you receive the connection data by email? Or is it something that you set up by yourself?
Sometimes you only have to put the host, user and the password.
Sometimes it is necessary to indicate a specific folder (path), which can be "www", or something like this.
I await a complement.
Most hosting plans have a root folder designated by the hosting company where all your public facing pages and assets go. If you try to upload files outside the server's root folder, nobody can see them.
My web host uses public_html as the root. Some other hosts use www or htdocs or html. It varies by hosting plan and the type of server you have. So if unsure, check with your host.
