Application Request Routing (ARR)
Reverse proxy issue for 2+ GB file upload

Does anyone know how to enable uploading files more than 2gb via IIS reverse proxy?
Currently the upload process gets stuck at 2gb of uploaded data and returns HTTP 500
Setting "maxAllowedContentLength" to 4gb does not resolve the issue.
We use IIS 10 with ARR3 running on Windows Server 2016 x64.
Thanks in advance

Hi Nick Bruscetto,
Manually edit the ApplicationHost.config file add a value that matches the size of the Content-Length header that the client sends as part of the request.
<requestLimits maxAllowedContentLength ="<length>" />
