The value for the property 'maxRequestLength' is not valid. The error is: The value must be inside the range 0-2097151.

You are setting a value that's nor acceptable and hence set it to something which is in the range.

For example if you want to upload 4 MB file value must be

4 x 1024 = 4096.

And for 10 MB file

10 x 2014 = 10240.

Thus set the value accordingly.

To resolve this issue you need to configure the settings of your server. Please do the following steps:

Go to c:\windows\system32\inetsrv\config\applicationHost.config and change Code:

<section name="requestFiltering" overrideModeDefault="Deny" />

to:

<section name="requestFiltering" overrideModeDefault="Allow" />

then Add to your application's web.config the following code:

 <system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength ="2147482624" /><!--this value in bytes~2GB-->
        </requestFiltering>
    </security>
    <system.webServer>

Here in web.config find the <system.web> section and the httpRuntime key. Modify the maxRequestLength and executionTimeout attributes of this key.

For example:

 <system.web>
         <!-- Uploading file size and timeout restriction -->
         <httpRuntime executionTimeout="540000" maxRequestLength="2097151"/> <!-- ~2GB -->
    </system.web>

Note:

• The maxRequestLength value should be specified in kilobytes. The default value is 4096 KB (the same as 4 MB).
• The executionTimeout value should be specified in second
