response: 413 Request Entity Too Large

When POSTing a request which can contain one or more files (as base64 string) I get this error response:

ERROR 2018-11-22 09:54:18,244 [13 ] Mvc.ExceptionHandling.AbpExceptionFilter - The remote server returned an unexpected response: (413) Request Entity Too Large. System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (413) Request Entity Too Large. at System.Runtime.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result) at System.ServiceModel.Channels.ServiceChannelProxy.TaskCreator.<>c__DisplayClass1_0.b__0(IAsyncResult asyncResult) --- End of stack trace from previous location where exception was thrown --- at ...

I have searched on how to resolve this but I get redirected to WCF solutions all the time.

I have added the following to the web.config of my WebApi project but it doesn't seem to make a difference.

<configuration>
  <system.webServer>
    ....
    <asp>
      <limits maxRequestEntityAllowed="2147483648"/>
    </asp>
    <serverRuntime uploadReadAheadSize="2147483647" />
  </system.webServer>
</configuration>

Can anyone help me or point me to the right resource?

For me I had to do in the web.config setting using maxAllowedContentLength and also an attribute on the action that was reading the file. I'm working on a .NET Core 3 application hosted on IIS.

Web.config or applicationHost.config on ASP .Net Core:

<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="2147483648" />
        </requestFiltering>
    </security>
    ...
</system.webServer>

Locate applicationHost.config under

<YourProjectFolder>/.vs/<YourProjectName>/config/applicationhost.config

If it still does not work, add attribute on the Action of the Controller:

[DisableRequestSizeLimit]
[HttpPost]
public async Task<IActionResult> PostMyFile()
{
   ...
}

There are two limits you need to change. Kestrel and IIS.

You can change the MaxRequestBodySize limit of Kestrel in Program.cs.

public static IWebHost BuildWebHost(string[] args)
{
    return WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseKestrel(options =>
        {
            options.Limits.MaxRequestBodySize = long.MaxValue;
        })
        .UseIISIntegration()
        .Build();
}

And the limit for IIS can be changed in web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="2147483648" />
      </requestFiltering>
    </security>
  </system.webServer>
</configuration>

I think, you may need to modify your web.config then add "maxRequestLength" and "maxAllowedContentLength"

<system.web>
    <compilation debug="true" targetFramework="4.5.2"/>
    <httpRuntime targetFramework="4.5.2" maxRequestLength="50240" executionTimeout="600"/> <!-- in Kb  -->
  </system.web>
  <system.webServer>
    <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="52428800" /> <!-- in byte (50 Mb) -->                                               
      </requestFiltering>
   </security>
