Link failure

I can't share a link to any files from both my accounts because an error keeps popping up "We weren't able to share your file. Please try again later". I have updated the app and repaired the installation, changed some security and general things in settings, tried sharing different files fromn different accounts and nothing seems to work. It also doesn't work while sharing by email or by adding other people to the file. What do I do? 

I use Windows 10.
