Skype For Business Broadcast

Hello All,

we are trying to implement Skype for business broadcast. We are running hybrid environment for SFB.

SFB:2015 Client:2016

We have enabled the broadcast settings and enabled the settings as per the following forum.

https://docs.microsoft.com/en-us/skypeforbusiness/deploy/configure-skype-meeting-broadcast

Policy: Boradcastmeetingpolicyallenbaled has been enabled in my profile.

I have the ability to create the meeting. When i try to click join the event, Lync/S4B 2016 client pop up and it closed straight away saying "an error occured during the skype meeting."  I dont have any problem opening as attendee.

any help will be appreciated.
