ERROR configuring IIS to enable proxy

    Applies to:
  • Legacy SecureAuth IdP
Deployment model:
  • On Premises
  • SecureAuth IdP Version Affected:  9.3+



    When upgrading to 9.3 the Updater displays this error:

    Begin: update system components... 
    Begin: installing IIS components... 
    Configuring IIS to enable proxy... 
    ERROR configuring IIS to enable proxy: System.Runtime.InteropServices.COMException (0x80070490): Filename: \\?\C:\Windows\system32\inetsrv\config\applicationHost.config 
    Error: The configuration section 'system.webServer/proxy' cannot be read because it is missing a section declaration

    at SecureAuthUpdater.ApplianceManager.InstallIISComponents()

    End: update system components



    IdP 9.3 requires the IIS component called Application Request Routing.

    ARR and 2 more installers are a prerequisite for the updater.




    Extract the SecureAuth 9.3 Updater to a folder on the D: drive and run the following installers prior to upgrading:
    <updater path>MFCApp_Bin\Extras\.NETCore2HostingComponents\dotnet-hosting-2.1.3-win.exe
    <updater path>MFCApp_Bin\Extras\ReverseProxyComponents\requestRouter_amd64.msi
    <updater path>MFCApp_Bin\Extras\ReverseProxyComponents\rewrite_amd64_en-US.msi
