filezilla here also. It has a problem sometimes – it says it’s connected but there are no connections but I think it’s more servers problem.
I have observed the opposite: it states it’s disconnected from server, yet the upload continues Nothing to complain

FileZilla. It’s not perfect, but I couldn’t find a better alternate.
I even use it for my website.
