I had similar issue  I resolved by changing the requestlimits maxAllowedContentLength   40000000  section of applicationhost config file  located in  C  Windows System32 inetsrv config  directory  Look for security Section and add the sectionGroup    lt sectionGroup name  requestfiltering  gt       lt section name  requestlimits  maxAllowedContentLength   40000000    gt   lt  sectionGroup gt     NOTE delete    lt section name  requestfiltering  overrideModeDefault  Deny    gt

lt configuration gt       lt system web gt           lt httpRuntime maxRequestLength  1048576    gt       lt  system web gt   lt  configuration gt    From here   For IIS7 and above  you also need to add the lines below     lt system webServer gt      lt security gt         lt requestFiltering gt            lt requestLimits maxAllowedContentLength  1073741824    gt         lt  requestFiltering gt      lt  security gt    lt  system webServer gt

The following example Web config file will configure IIS to deny access for HTTP requests where the length of the  Content-type  header is greater than 100 bytes      lt configuration gt      lt system webServer gt         lt security gt            lt requestFiltering gt               lt requestLimits gt                  lt headerLimits gt                     lt add header  Content-type  sizeLimit  100    gt                  lt  headerLimits gt               lt  requestLimits gt            lt  requestFiltering gt         lt  security gt      lt  system webServer gt   lt  configuration gt    Source  http   www iis net configreference system webserver security requestfiltering requestlimits
