@firebase/firestore: “Firestore (11.9.0): Could not reach Cloud Firestore backend. Connection failed 1 times. Most recent error: FirebaseError: [code=unknown]: Fetching auth token failed: Firebase: Error (auth/network-request-failed).\nThis typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.”
First, I would double-check check environment variables, API keys. Willing to bet it’s one of those. After that, check your network stuff. VPN, firewall, Emulator?, start questioning ports.
