Well, the error says that the problem is on the File Share side and not in SPO...does the application have the required permissions to read information from that path?

Yes. The console application is running on my user login and has full permission. Still I get the error in FileMode.Open 


using (FileStream o365FileStream = new FileStream(o365FilePath, FileMode.Open))
Microsoft.SharePoint.Client.File.SaveBinaryDirect(o365Context, o365ServerRelativeUrl, o365FileStream, true);

Not sure it relates, but I had this same error trying to run a program, very recent security update that caused this issue for me.  When I right click and 'Run as Administrator' the problem disappeared.
