Hey there! I totally get wanting to catch your home team on the big screen. Let's work through the casting issue with your FloHockey app on your iPhone to your TV.

To start, can you tell me a bit more?
- What type of TV or casting device are you trying to cast to? (Smart TV brand/model, Chromecast, Apple TV, etc.)
- When you try casting from your iPhone, do you see your TV/device listed as an option?
- Have you been able to cast any other apps from your iPhone to the TV before?

Meanwhile, here’s a straightforward rundown of steps to try:
1. Check your Wi-Fi: Make sure your iPhone and TV/casting device are connected to the same Wi-Fi network. This is critical for casting to work.
2. Restart the FloSports app and casting device: Close the FloHockey app entirely on your iPhone (swipe it away from the app switcher) and then reopen it. Also, power cycle your TV/casting device (turn it off, wait 10 seconds, then turn it back on).
3. Try casting again: From the FloHockey app, look for the casting icon (it usually looks like a little TV or screen). Tap it and select your TV or casting device.
4. Update apps and TV firmware: Ensure your FloSports app and your TV’s software are up to date. Sometimes, outdated software can cause casting hiccups.
5. Test AirPlay if available: Since you’re on an iPhone, you can also try AirPlaying the screen to your TV (if your TV supports AirPlay). Swipe down to access Control Center, tap Screen Mirroring, then select your TV.

If after these you’re still not able to cast, it might help to check the FloSports support for casting specifically on iOS apps, or there could be a temporary server or app bug.

Could you let me know the details I asked above and what you’ve tried so far? That way, I can tailor the next steps precisely for you.
