I am getting error when trying to read excel file from Request.Files (InputStream), but error came up just from a windows server machine. any idea about something missing?

EPPlus version is 4.5.2.1

Error Line:

    foreach (string file in Request.Files) {
        HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
        using (var xls = new ExcelPackage(hpf.FileStream))

  //<--- ERROR LINE

Error message:

Object reference not set to an instance of an object.

The issue was solved, the reason for the issue was the files were encrypted and when uploading they could not be read.
