LG TV not playing video/playing wrong video with ConnectSDK - ios

Question

I am trying to play a MP4 video on a LG TV using the Connect SDK 1.4.1. We have a working implementation with Chromecast and Apple TV.
When first starting our app, we are able to successfully connect to the LG TV. When trying to play one of our own videos the first time, we receive no response from the Connect SDK, nor do we see the video play on the TV. In the console output, it appears that the TV disconnects from the app. The console output can be seen in the Console Output below.
However, we are able to successfully play the Sintel video provided in your demo. After playing that video, any future attempt to play a video from my app results in the Sintel video being played instead.
I used Charles to redirect the path to the Sintel video, to a video used in my app, and found that the video played fine. This appears to be a communication issue between the App and the TV causing this unintended behavior.
Am I doing something wrong that is specific to the LG platform? Is there any additional information I can provide to solve this problem?
Thank you!
