ssrs error Maximum request length exceeded

Question

I open a report file (created in SSRS 2014) in report builder of SSRS 2016 in order to save it into report manager site OR preview it, I get this error:

System.Web.Services.Protocols.SoapException: There was an exception running
the extensions specified in the config file. ---> System.Web.HttpException: 
  Maximum request length exceeded.
at System.Web.HttpRequest.GetEntireRawContent()
at System.Web.HttpRequest.get_InputStream()
at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
   --- End of inner exception stack trace ---
at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, 
 HttpContext context, HttpRequest request, HttpResponse response, Boolean& 
   abortProcessing)

Upload option on report manager site doesn't work either.

Answer 1

This error is due to the size of the .rdl file. My .rdl file was about 4MB, so I only needed to increase the value of maxRequestLength at httpRuntime line on web.config file and then, restart iis:

 httpRuntime executionTimeout = "9000" maxRequestLength="500000"

In this case, I set the max size to 5 MB.
