How to get in an archive of unavailable FTP?
 

Does anybody can find an archive of a no longer working FTP? I used to use this service: https://web.archive.org/ , I see that there were copies made, but no files can be reached. Is there a way to open it?
FTP was available here: f*p://volna:[email protected]/
Before it was available here: f*p://volna:[email protected] - this link is not read by web archive
