Redeployed MVC5 dlls on IIS7.5 HTTP 500 Internal Server Error

Question

I am getting 500 Internal Server Error and finding no clue about the problem

However I have just updated applications dll and in browser it is not showing any HTTP500 error details

There is warring in Failed Request Tracing

ModuleName ManagedPipelineHandler

Notification 128

HttpStatus 500

HttpReason Internal Server Error

HttpSubStatus 0

ErrorCode 0

ConfigExceptionInfo

Notification EXECUTE_REQUEST_HANDLER

ErrorCode The operation completed successfully. (0x0)

I have tried these webconfig settings but there is no error details in browser

<system.web>
<customErrors mode="Off"/>
<compilation targetFramework="4.6" debug="true">
</system.web>

<system.webServer>
<httpErrors errorMode="Detailed" />
<asp scriptErrorSentToBrowser="true"/>
</system.webServer>

this error come when client can't get response from your server.It may me due to your server permission or A Coding Error in .htaccess please contact your admin for this error — Suyash Kumar Singh

I have solved it by these steps

Publish settings ->  Unchecked "Precompile during publishing"

IIS was throwing 404.3 on precompiled version
