Description

I can connect to the database emulator on first startup of app but when I disconnect and then reconnect I can no longer connect.

Reproducing the issue

Setup the firebase config as folllows

 FirebaseDatabase realtimeDatabase() {
   
    FirebaseDatabase db = FirebaseDatabase.instanceFor(
      app: _firebaseApp,
      databaseURL: DefaultFirebaseOptions.DATABASE_HOST,
    );

    if (kDebugMode) {
      db.setLoggingEnabled(true);
      int port = int.tryParse(DefaultFirebaseOptions.FDB_EMULATOR_PORT)!;
      db.useDatabaseEmulator(DefaultFirebaseOptions.FB_HOST, port);
    }

    db.setPersistenceEnabled(true);
    return db;
  }

DATABASE_HOST is setup as emulator URL here
"http://$FB_HOST:$FDB_EMULATOR_PORT/?ns=projectname"

Call goOnline, then goOffline, then try to go back online using goOnline

Firebase Core version

Additional context and comments

No response

[muzzah]

I should add that problem persists if the FB_HOST value is IP address of emulator host, 10.0.2.2 (for android emulator) or a hostname pointing to emulator host. The hostname for the emulator host value is not 127.0.0.1 eventhough the logs actually reflect this.

[SelaseKay]

Hi @muzzah, thanks for the report. From your logs, I can see you're using port 5002. Could you try port 9000(preferred default) as specified in the Port Configuration Documentation for database?

[SelaseKay]

Also, ensure you have configured the port in your firebase.json file.
Reference: https://firebase.google.com/docs/emulator-suite/install_and_configure#security_rules_configuration

[muzzah]

My emulators are configured to start on the specified ports as per my firebase config file

{
  "firestore": {
    "rules": "firestore.rules"
  },
  "emulators": {
    "firestore": {
      "port": "5100",
      "host": "0.0.0.0",
      "indexes": "firestore-indexes.json"
    },
    "auth": {
      "port": "5001",
      "host": "0.0.0.0"
    },
    "database": {
      "port": "5002",
      "host": "0.0.0.0"
    },
    "logging": {
      "host": "0.0.0.0"
    },
    "hub": {
      "host": "0.0.0.0"
    },
    "ui": {
      "enabled": true,
      "host": "0.0.0.0",
      "port": 4000
    }
  }
}

Do you want me to change these values to the standard ports? The app can connect to the emulator on a fresh install and start. Once disconnected it cannot connect to the emulator on the second and latter tries

[muzzah]

Auth and firestore emualtors work fine btw. The app has no problem connecting to those emulators.

Hi @muzzah, kindly share a minimal repo link reproducing this issue. One I can clone to investigate further.
