    # Run Flask on the same port? No, it's occupied.
    # We'll run Flask on port 7860 and use it as a reverse proxy, or run on a different port.
    # Actually, we can run Flask on 7860 and forward requests to 3x-ui on a different port.
    # But 3x-ui is listening on 7860. This is conflicting.
    # Solution: Run 3x-ui on 8080, and Flask on 7860 and proxy.
    # Or run Flask on 7860 and 3x-ui on another port. Let's do Flask on 7860 and proxy.
    # But then we need to implement a proxy in Flask.
    # It's more complex. The start.sh approach is simpler.
