Issue with Re-streaming RTSPS using Wowza (Waiting for Stream)

I am trying with rtsps:// source url. When I follow Stream from an IP camera over RTSP to Engine steps using wowza dashboard it was saying rtsps:// not supported protocol. only rtsp is in that list.

But I tried with REST APIs for creating streamfile & action connect apis..

In the Wowza dashboard console Incoming Streams section can seeing my new stream with postfix .stream and status as Waiting for Stream. I tried with ffplay rtsps://…. it works fine there. I wait for some time still the status did not change. Any suggestions on this?
