FTP Login sign in problem

:-La :-La I have an issue with the login to my FTP servers. I entered all information in the backup destination regarding the FTP. When I click sign in nothing happen just a white box without any tree information.

I tested my FTP connection in three differents software, and I have no issue to sign in.

Can someone as any experience on that kind of issue?

Thanks a newbie :-La :-La
