File Size

Is there a max file size that is allowed to be used when uploading a file?  I am trying to upload an excel file to a webserver but it fails.  If I remove enough data from the file to shrink the file size, the upload then works.
I don't believe it is a restriction from the webserver because I can ftp the full size file without a problem.

Also, is there a way to see why the upload fails?  All I get is a red x in the upload box but I have no idea as to why.

Hi Richard,   
Thanks for contacting Syncfusion support.  
Query: “Is there a max file size that is allowed to be used when uploading a file?” 
Yes, In the UploadBox control, You can restrict the files from being browsed using the FileSize property. When you do not use this property, it takes a default size, 31457280B, that is, 31MB. When this size exceeds, we cannot browse the file. 
Please refer to the help Documentation link: https://help.syncfusion.com/aspnetmvc/uploadbox/file-size  
Query: “is there a way to see why the upload fails?” 
 Yes, you can find the error details in error event in uploadbox. 
Refer to the code snippet:  
    <script type="text/javascript"> 
        function fileerror(args) {
