A lot of connection errors when send requests in Timer.periodic

[justjew]

I need to send a POST request every minute. So I use Timer.periodic for it. In debug mode there is no problem. But in production there are hundreds of: SocketException: Failed host lookup Connecting timed out [0ms] SocketException: Software caused connection abort SocketException: Bad file descriptor HandshakeException: Connection terminated during handshake

I see them in Sentry. I am absolutely sure there was no problems with internet connection. Besides, half of requests reach the destination.

void _startSendingDeviceActivity() {
  _sendDeviceActiviryTimer?.cancel();
  _sendDeviceActivity();
  _sendDeviceActiviryTimer = Timer.periodic(const Duration(minutes: 1), _sendDeviceActivity);
}

Future<void> _sendDeviceActivity([_]) async {
  final DeviceInfo deviceInfo = await DeviceActivity.getDeviceInfo();
  _userApi.sendDeviceActivity(deviceInfo);
}

@override
void dispose() {
  _sendDeviceActiviryTimer?.cancel();
  super.dispose();
}
