Teams Outgoing Webhook works for me but can't be run by my teammates

I have a simple python server hosted on my machine using NGROK. The server listens for an outgoing webhook from teams that runs a script. The webhook works fine for me but when my teammates "@mention" the webhook it doesn't hit the server. I'm not sure why this is, because if it can reach it from teams when I hit it why wouldn't it work when they do. My first thought is because it's hosted on my machine but NGROK says it "exposes local web servers to the internet" so if I take that at face value maybe it's a teams issue?
