i use this configuration but it says warning that the servicePointManager is not element of settings < system.net > < settings > < servicePointManager expect100Continue="true" / > < securityProtocol > < add value="Tls11" enabled="false" / > < /securityProtocol > < /settings> < /system.net>
I would rather disable it in IIS server when setting up the bindings as explained here.
