My issue is similar to this one: /forum/developer-forum/CMS/Thread-Container/2020/5/import-large-export-files/?_t_id=oNIRkMs6Am_3CI84xb_lvg%3d%3d&_t_uuid=RvEi1M2NS%2fyJdg0Ws4nadQ&_t_q=The+page+was+not+displayed+because+the+request+entity+is+too+large&_t_tags=language%3aen%2csiteid%3a4ba62c03-2627-4a1e-8939-9db6098db0eb%2candquerymatch&_t_hit.id=EPiServerWorld_ContentTypes_WebFormTypes_ThreadPageType/_22f19c27-9176-4cce-8461-88c3cf1f791e_en&_t_hit.pos=1

I updated the <system.webServer> node in my web.config to this:

<security>
    <requestFiltering>
        <requestLimits maxAllowedContentLength="2147483648" />
    </requestFiltering>
</security>

But I'm still getting the same error. The bytes here should be about 2 GBs, while my export file is around 250 MBs. I'm having this issue in pre-prod. I updated the web.config in integration, promoted the changes to pre-prod, and the error continues. Any ideas what's going on here?

Thanks
