You might have to use StreamNameAlias so you can use a simple name in the player instead of the rtsp url:

But I’m not sure if it’s necessary, in JW player it is not necessary.
What about the version numbers of the player and plugin? They are different, one is 3.1.5 the other is 3.1.3. I’m not sure if that matters either, but it might.
