[JMVoid]

I run "flutter build macos" to build release version code on a project and enter Contents/Macos folder and execute binary program. a Exception throw as following:
[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: SocketException: Failed host lookup: 'www.bitstunnel.com' (OS Error: nodename nor servname provided, or not known, errno = 8).
#0 IOClient.send (package:http/src/io_client.dart:33)

#1 BaseClient._sendUnstreamed (package:http/src/base_client.dart:176)
#2 BaseClient.get (package:http/src/base_client.dart:35)
#3 get. (package:http/http.dart:46)
otherwise, I execute "flutter run -d macos", the project is run well. have any idea of this issue??

The necessary entitlement, and the process for enabling it, is documented here. Note that you should not use the UI pictured above to enable it, as explained in the documentation.

@lesnitsky Please don't point people to the UI, which, as documented, is unlikely to work correctly. Also, it's not clear why you are instructing @JMVoid to enable server capabilities as nothing about this report suggests an intent for the app to be a server. @JMVoid You should start with enabling just the client entitlement unless you know that your application intends to accepting incoming connections. Enabling the server entitlement unnecessarily adds a significant attack surface to your application.

Closing as this is almost certainly a configuration error in the project rather than a bug.
