php - uploading files stuck on pending -

php - uploading files stuck on pending -

i have web application running on server 2012 iis , php version 5.5.11.

i have simple form uploading files server

<div class="pdfupload"> <h1>upload files</h1> <form action="/<?php echo $user?>/upload" method="post" enctype="multipart/form-data"> <input type="file" name="files[]" multiple /> <input type="hidden" name="test_id" /> <input type="hidden" name="points" /> <input class="uploadpdfsubmit" type="submit" value="upload files" /> </form> </div>

the form worked fine , able upload files, until few days ago. of files uploaded (notepad or empty doc files upload pdf or doc content wont upload) not size related isuue cause able upload big notepad file.

the problem accurs while im connected home network - tried 3 other networks , there no problem.

the files wont upload stuck on pending - , going network tab in chrome see request isnt created properly. under headers see warning sign provisional headers shown.

i have no thought causing strang behavior
