First, thank you for all the work on this, it is great!

A couple of months may ago, it is has stopped working. I only now had a chance to check the container logs. I'm getting the following error. Any help would be appreciated!

Here is my Docker Compose if helpful (I run it with wyze bridge as well but I excluded that part of the compose file):
services:

# Image to pull, adjust the :suffix for your version tag
#image: registry.gitlab.com/adam.stanek/nanit:v0-7

image: indiefan/nanit:latest
# Makes the container auto-start whenever you restart your computer
restart: unless-stopped
# Expose the RTMP port
