Can't get files over 16k to upload. Getting the "maximum request length exceeded" error despite configuring the web.config file to be the following for the site:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<httpRuntime targetFramework="4.5" maxRequestLength="1048576" executionTimeout="3600" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="1048576000" />
</requestFiltering>
</security>
<directoryBrowse enabled="true" />
</system.webServer>
</configuration>

Exact Error: {"type":"Error","fileName":"dmxConnect.asp","errorNumber":-2147467259,"message":"maximum request length exceeded","stack":[]}

Any help. Running Windows Server 2019 - brand new install on AWS. I've read the default should be well above 600kb and it failed without the web.config file in place too.

The test file is HERE (dev.mydisc.info/files/anode.jpg)

Hello Steve,
Please check the solution to this here: stackoverflow.com/questions/3853767/maximum-request-length-exceeded

Doesn't my web.config file in the post look EXACTLY like the one in the article you mention? I've done this and it doesn't work. There's nothing more you can do to assist - no expertise you can offer beyond what the Internet says?

Hello Steve,
The error is not related to any of our extensions. We don't set limits for any of the tools, all the limits are set in your server configuration.
Please contact your hosting support/server admins so they can check what's wrong with the limits and why the web.config changes you made don't make any difference.

This was related to editing the ASP Limits Properties and none of the web.config items listed in the referred support article made any difference.
