@firebase/firestore: Firestore (5.0.4): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds

问题

I am working on an Angular 6 project. This is the error I get when I build with --prod flag, host and run. I've been sitting on this for a long time. Initially thought it was probably a problem with the firestore package and i waited. But now updated to firestore 5.0.4, the problem still exists.

This 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.

app.module.ts

Imports: [
    AngularFireModule.initializeApp(environment.firebaseConfig),
    AngularFirestoreModule
]

app.component.ts

constructor(public afAuth: AngularFireAuth,
          private afs: AngularFirestore,
          private db: AngularFireDatabase) {
    this._currentUser = this.afAuth.authState
      .pipe(
        switchMap((user: any) => {
           if (user) {
            console.log(user);
            return this.afs.collection('users').doc<User>(user.uid).valueChanges();
           } else {
             return Observable.create(null);
           }
        })
      );
}

FYI: Authentication still works.

You should enable Firestore in you Firebase Console. Do the following steps:

Open the Firebase Console, open or create a new project.
In the Database section, click the Get Started button for Cloud Firestore.
Select a starting mode for your Cloud Firestore Security Rules: Test mode or Locked mode
Click Enable.

Cloud Firestore and App Engine: You can't use both Cloud Firestore and Cloud Datastore in the same project, which might affect apps using App Engine. Try using Cloud Firestore with a different project. When you create a Cloud Firestore project, it also enables the API in the Cloud API Manager.
