Android AppWidget using WorkManager experiencing network issues

Question

I have an application in production that contains an AppWidget that schedules periodic refreshes via a WorkManager CoroutineWorker. My RefreshWidgetWorker simply requests some data from a Retrofit service & then persists that data via a Room DAO. I am receiving hundreds of crash logs of network connectivity issues & reports from users that the widget will not load for them. The exception is typically:

java.net.UnknownHostException: Unable to resolve host "[my-server]": No address associated with hostname

Although I've also seen:

java.net.SocketTimeoutException: failed to connect to (port ###) from (port #####) after ####

The flow is as follows:

widget onUpdate() gets called (every hour) -> check X duration since last refresh -> schedule RefreshWidgetWorker -> request from remote api -> display widget view -> persist cached data

My AppWidgetProvider (paraphrasing) looks like the following:

override fun onUpdate(context: Context, appWidgetManager: AppWidgetManager, appWidgetIds: IntArray) {
    GlobalScope.launch {
        if (timeSinceLastRefresh >= refreshThreshold) {
              val initialWorkRequest = OneTimeWorkRequest.Builder(RefreshWidgetWorker::class.java).setInputData(/*requestData*/).build()
              WorkManager.getInstance(context).enqueueUniqueWork(
                    REFRESH_WIDGET_WORK_NAME, ExistingWorkPolicy.KEEP, initialWorkRequest
              )
        }
    }
}

My RefreshWidgetWorker looks like:

class RefreshWidgetWorker(val context: Context, workerParams: WorkerParameters) :
    CoroutineWorker(context, workerParams), KoinComponent {
    private val dataService: DataService by inject()

    override suspend fun doWork(): Result {
        val d = dataService.getData()
        val views = RemoteViews(context.packageName, R.layout.widget_layout).apply {
            setTextViewText(R.id.textView, d.item)
        }
        AppWidgetManager.getInstance(context).updateAppWidget(widgetId, views)
        cache.put(d)
        return Result.success()
    }

And DataService is just a simple Retrofit service:

Retrofit.Builder()
        .baseUrl(Constants.API_BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .addCallAdapterFactory(RxJava2CallAdapterFactory.createWithScheduler(Schedulers.io()))
        .client(
            OkHttpClient.Builder().connectTimeout(2, TimeUnit.SECONDS)
                .readTimeout(2, TimeUnit.SECONDS).writeTimeout(2, TimeUnit.SECONDS).build()
        )
        .build()
        .create(DataService::class.java)

I've been unable to reproduce this issue on my own device & am unsure if it has to do with spotty mobile networks or a system optimization that is preventing my requests from going through. I'd appreciate any insight anyone might be able to provide as I have been stumped on this issue for a while.
