rtmp connection fails from IE

Hi, I’am trying to connect to my wowza streaming live app via rtmp using official example with flash 11. In chrome and firefox everything works fine, but in IE and edge it simply doesn’t work. I’am using this example https://www.wowza.com/resources/3.6.0/examples/WebcamRecording/FlashRTMPPlayer11/player.html (also used the local example from installation folder). What should I do? IE and Edge must be able to do what i want to do, I’am pretty sure there is a misconfiguration by my side.
