Failed to load resource: net::ERR_INCOMPLETE_CHUNK

I use IExplorer 11 in Windows 8.1, and IIS and ASP.NET 4.6.1 in Windows Server 2008 R2.

My ASP.NET application is WebForms and using UpdatePanels.

I have handlers config:

<httpHandlers>

  <remove path="*.asmx" verb="*" />
  <add path="*.asmx" verb="*" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />
  <add path="*_AppService.axd" verb="*" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />
  <add path="ScriptResource.axd" verb="GET,HEAD" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />

and system.webServer.handlers:

  <remove name="ScriptResource" />
  <add name="ScriptResource" 
       verb="GET,HEAD" path="ScriptResource.axd" 
       preCondition="integratedMode" 
       type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

Now, I tried to access my web application via HTTPS. But I get an error now, before not, another older tests was right.

I get error in Console (F12 for Developers in IE):

Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING

Full message in Console:

I try using

scriptResourceHandler enableCompression="false" enableCaching="true"

 <system.web.extensions>
    <scripting>
      <!-- Test: Error net::ERR_INCOMPLETE_CHUNKED_ENCODING -->
      <scriptResourceHandler enableCompression="false" enableCaching="true" />

    </scripting>
  </system.web.extensions>

and I try disabled compression:

<!-- DISABLED GZIP

<urlCompression doStaticCompression="true" doDynamicCompression="true" dynamicCompressionBeforeCache="true"/>
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" sendCacheHeaders="true" cacheControlHeader="max-age=31536000" dynamicCompressionDisableCpuUsage="90" staticCompressionDisableCpuUsage="90" dynamicCompressionEnableCpuUsage="0" staticCompressionEnableCpuUsage="0">

    <add mimeType="*/*" enabled="false"/>
  </dynamicTypes>
</httpCompression>

Any suggestions? How-to do good troubleshooting about it ?

UPDATE: I test in Chrome, and I get the same error.

I have seen F12 Console log:
