am See the same issue as well
We recently made some operating system changes. This led to a nice boost in performance (which was expected) but seems to have caused an issue with FTP over SSL in PHP.
I’m currently trying to find the solution to this.
UPDATE: After some additional investigation, it looks like that there is a compatibility issue in the configuration between the free hosting FTP server and the client area. This is going to be hard to fix properly, but I’ve implemented a workaround that should allow the FTP features to work again.
