How do I trouble shoot an upload error I am getting on Azure. RadAsyncUpload works fine on my local machines but when deployed to the server I get

"Failed to load resource: the server responded with a status of 500 (Internal Server Error)"  & "Uncaught Error while uploading, HTTP Error code is: 500"

Hi Mark,

You can temporarily enable the custom errors so you can see a detailed stack trace. This should direct you to what is causing the issue and what a possible solution would be.

We have received a number of similar reports where the Azure firewall (WAF - Web Application Firewall) was blocking the web resource requests or modifying the query parameters. You can check with your Network administrators which settings exactly are affecting the web resource requests and tweak them so the application can function properly.
