Description

Hi, i’m using realm for a react native application. I receive SyncError: Failed to connect to sync: Host not found (authoritative) error when turn off wifi. But i have read mongo realm is offline first…

I open realm like this:

function AuthProvider() {
  const [visible, setVisible] = useState<boolean>(false);
  const [error, setError] = useState<string>('');

  const user = useUser();
  console.log('user', user);

  const realmAccessBehavior: Realm.OpenRealmBehaviorConfiguration = {
    type: Realm.OpenRealmBehaviorType.DownloadBeforeOpen,
    timeOutBehavior: Realm.OpenRealmTimeOutBehavior.OpenLocalRealm,
    timeOut: 3000,
  };

  return (
    <RealmProvider
      schema={[
        Invoice,
        Operator,
        Customer,
        Report,
        ReportDetail,
        Manpower,
        Material,
        RightToCall,
      ]}
      sync={{
        flexible: true,
        newRealmFileBehavior: realmAccessBehavior,
        existingRealmFileBehavior: realmAccessBehavior,
        initialSubscriptions: {
          update(subs, realm) {
            subs.add(realm.objects(Invoice));
            subs.add(realm.objects(Customer));
            subs.add(realm.objects(Operator));
            subs.add(realm.objects(Report));
          },
          rerunOnOpen: true,
        },
        onError: (_session, err) => {
          console.log('error', err);
          setError(err.message);
          setVisible(true);
        },
      }}>
      <App />
      <ErrorDialog
        errorTitle="Errore di Sincronizzazione"
        errorMsg={error}
        visible={visible}
        setVisible={setVisible}
      />
    </RealmProvider>
  );
}

Host not found (authoritative) means you are offline. It is a bit confusing that the sync client reports it as an error.

From the title of the issue, it sounds like you are experiencing a variation of https://github.com/realm/realm-core/issues/7349. We are actively working on a fix.
