[OBSOLETE] LANnouncer with IFTTT (2016)

Hey guys, I’m stumped and could use some help. I have Lannouncer running on an android tablet. Here’s what works:

I can use a web browser to send speak and chime commands to it using the tablet’s internal IP address.
I can use WebCoRE to send an http speak command via my WAN (with port 1035 forwarded).
I can successfully ping the tablet

I verified the correct IP address and port are configured in the LANnouncer thing.

What I can’t do is get Big Talker or WebCore to work with it. When I look in the IDE, I see them both send the speak commands but I don’t get anything from Lannouncer.

Because I can access Lannouncer via my internal and external networks, I’m guessing the issue has something to do with SmartThings. I bought the tablet specifically to run Lannouncer, so any help is very much appreciated.
