Add Sunrise Sunset to Time Plan Settings

I've been attempting to implement the day/night switch via Blue Iris 5.9 on my T54IR-ZE-S3 running Web Version V5.01.0.2308726 but haven't gotten past this error "Web: No stream: 404." I'm using the api calls listed in this post: I've removed special characters from my password, tried with and without the port setting in the url. No Luck. Searching on this error and didn't come across anything that helped. I'm using the presets, on call... section of PTZ/Control. I've left my working mode as Customized Scene. Appreciate any help - yes I realize I can just keep using the Day/Night Switch but where's the fun in that? It annoys me that this should be working.

If the camera GUI is the blue/white color, then the utility doesn't work - it only works for the older black/grey/orange GUI.
