Plupload file error 5 mb - asp.net

Question

I am using the plupload queue widget but it won't work.
Everytime i tries to upload a file larger than 5 mb it went to 100% and gives me a http Error.
When i upload a file from 3 mb this wil work perfectly and after 100% he gives me a green ok sign.
$(function () {
$("#uploader").pluploadQueue({
runtimes: 'html5,html4,flash,gears,silverlight,browserplus',
url: '/Upload/Upload',
max_file_size: '10mb',
post_max_size: '10mb',
upload_max_filesize: '10mb',
chunk_size: '10mb',
unique_names: true,
urlstream_upload:true,
multipart: true,
multiple_queues: false,
filters: [
{title: "Foto's", extensions: "jpg,gif,png"},
{title: "Video's", extensions: "wmv,avi" },
{ title: "Microsoft Office", extensions: "docx,xslx" },
{ title: "Zip files", extensions: "zip" },
],
preinit: {
FileUploaded: function (up, file, response) {
var data = response.response; //$.parseJSON(response.response);
$('<input>').attr({
type: 'hidden',
name: 'fileId' + data,
value: data
}).appendTo('#uploadFinishedForm');
if (data.error == 1) {
uploader.trigger("Error", { message: "'" + data.message + "'", file: file });
console.log('[Error] ' + file.id + ' : ' + data.message);
return false;
}
},
UploadComplete: function (up, files) {
window.setTimeout(function (form) {
// $('#uploadFinishedForm').submit();
$('.nextButton').append('<input type="submit" class="btn btn-large btn-success submit-btn" value="Transfer" />');
}, 2000)
},
Init: function (up, info) {
$('#uploader_container').removeAttr("title");
}
}
});
$('#uploadForm').submit(function (e) {
var uploader = $('#uploader').pluploadQueue();
if (uploader.files.length > 0) {
uploader.bind('StateChanged', function () {
if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
$('#uploadForm').submit();
}
});
uploader.start();
} else {
$('#uploadInfo').html('Zonder foto\'s valt er niets te uploaden!');
}
return false;
});

Try to decrease the value of the chunk_size (1mb instead of 10mb by example):
chunk_size: '1mb'
