ASP.NET cannot get rid of "500-Internal Server error"

Question

I am creating an ASP.NET website that retrieves and inserts data inside CRM 2011. Everything went well, the page was deployed to the server, and it was ready for testing.

Suddenly, a new change appeared, and after I deleted the files on the server and reissued the project (I know it is not needed, but still ...). I could no longer access the website.

All I get is a 500-Internal Server Error There is a problem with the resource you are looking for and cannot be displayed.

I tried to enable the debug function with debug = "True" in the page title, I set

<customErrors mode="Off"/> <compilation debug="true" targetFramework="4.5"/> 

In the web.config file, I also tried adding

 <httpErrors errorMode="Detailed" /> 

but none of them helped improve the error message.

My web.config file:

When the page starts, an error message appears. Error message: System.ServiceModel.FaultException error occurred while checking the security for the message: An error occurred while checking the security for the message.

Section where the error occurs:

  RetrieveAttributeRequest retrieveFreightTerm = new RetrieveAttributeRequest { EntityLogicalName = "account", LogicalName = "address1_freighttermscode", RetrieveAsIfPublished = true }; 

Any ideas?

Answer 1

I opened the website from the server running IIS, and I could see a detailed error page with all the information I needed.

Answer 2

Many times this happens after editing the web.config , we leave some tag closed or not correct. This also results in a 500 internal server error.

For your web.config test web.config pass this test, open it in Internet Explorer. If tags are skipped, IE will show you the corresponding error.
