[XOneto9]

Hi, After upgrade flutter 3.7.3, I've got an error message of network.

QueryResult(source: QueryResultSource.network, data: null, context: Context({}), exception: OperationException(linkException: ServerException(originalException: Connection failed, originalStackTrace: #0      IOClient.send

before upgrade It was good work

The message is like below.

getMemberWithProvider(String provider, String providerId) async {
    try {
      final client = config.getClient();
      final options = QueryOptions(
        document: Queries.getMemberWithProvider,
        variables: {
          'provider': provider,
          'provider_id': providerId,
        },
        fetchPolicy: FetchPolicy.noCache,
      );
      final result = await client.query(options); // here, error is happened

    } catch (e) {
      print(e);
    }
  }

The debug message of result

QueryResult(source: QueryResultSource.network, data: null, context: Context({}), exception: OperationException(linkException: ServerException(originalException: Connection failed, originalStackTrace: #0      IOClient.send

, parsedResponse: null), graphqlErrors: []), timestamp: 2023-02-13 01:28:09.866691)

Also I was set real url address like as: 'http://192.168.x.x:3000/graphql' And, My custom server is running on docker nodejs and mongodb. server is very good condition. of cause, I can connect mongodb with Mongodb compass.

only, the problem to connect server is just flutter....

what can I do to solve it??

Solved,

remove app on device, and re-computing computer.

and allow local network setting in my iPhone.
