Proxy error: Unable to draw graphic (null): Unable to load proxy.ashx?http://.......... status: 500

Question

Not sure how to debug this error that I keep getting in this app installed on a newer web server with Server 2012 R2 OS on it

http://gis.collincountytx.gov/electionpollingplace/

The same app is working just fine on an old web server with Windows 2008 R2 OS on it

http://gismap.collincountytx.gov/electionpollingplace/

The app has been developed from ArcGIS for Local Government where it says that requires .NET Framework 4.0

I'm wondering if my web server that has Server 2012 R2 with .NET Framework 4.5 may be the problem

It looks like a similar issue is here: Unable to load proxy

It would also be a good idea to make sure your ASP.NE feature is enabled as Kelly Hutchins‌ mentioned in the thread. You can find that info here: Running Web Applications on Windows Vista with IIS 7.0 and Visual Studio

Otherwise, I would compare your situation to the thread and see if your settings match.

2. Not sure hot to upgrade this one - web.config - the is no URL there

A few things that I can recommend is:

* Did you include your proxy.ashx, proxy.config and proxy.xsd files when you copied the application over to the new server?
* Did you update your web.config file for the new URL?
* Did you convert the website into an application in IIS?

Apart from that I would check the other settings in the new server in IIS to the old server IIS settings and check rights.
