Error 500 Maximum request length exceeded

[CCWeedcontrol]

I have an app built with Web Appbuilder Dev 2.2 with some layers off of ArcGis Online. I down loaded it and put it on my IIS. with a proxy. It seems as when i try to print with a certain layer i get print error. Network tab indicates the following. I am not sure what this means other than the maximum request length exceeded. Any help would be great.

Server Error in '/DotNetProxy2' Application.

If that was the URL it was complaining about then it would not exceed the limit.

I had to increase the runtime time out and max requestlength in the web.config file. Now it works fine

like so.

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="false" targetFramework="4.0"/>
  </system.web>
  <system.web>
<httpRuntime executionTimeout="100000" maxRequestLength="214748364" />
</system.web>
  <system.diagnostics>
    <switches>
      <add name="TraceLevelSwitch" value="Info" />
    </switches>
    <trace autoflush="true" indentsize="4">
      <listeners>
        <add name="agsProxyLogListener" type="System.Diagnostics.TextWriterTraceListener"
             initializeData="C:\Temp\Shared\proxy_logs\auth_proxy.log" />
        <remove name="Default" />
      </listeners>
    </trace>
  </system.diagnostics>
</configuration>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thank you, to add the

  <system.web>
    <httpRuntime executionTimeout="100000" maxRequestLength="214748364" />
  </system.web>

section to the Web.config of my dotnet proxy resolved my attachment size limit (ArcGIS enterprise/portal).

If you are using IIS for hosting your application, then the default upload file size is 4MB. To increase it, please use this below section in your asp.net web.config -

<configuration>
<system.web>
<httpRuntime maxRequestLength="1048576" />
</system.web>
</configuration>
For IIS7 and above, you also need to add the lines below:

<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="1073741824" />
</requestFiltering>
</security>
</system.webServer>
Note:

maxRequestLength is measured in kilobytes
maxAllowedContentLength is measured in bytes
