Let's suppose that I want to download some files that need passwords (in the server) to be downloaded. When, I try I get an error with problems to connect the service. Is it possible to provide any solution to this case? Thanks!

Yes, the relevant plugins need to be updated to support passworded links. Please post example links.

Here there are three protected downloads:

[filepost.com]

[filepost.com]

[filepost.com]

And in this case, the passport for all files is: 12ab
