Question: I have an observable that polls every 60 seconds. However, if user makes an action (i.e. success from another API call) in the component level I'd like to trigger that API call again but keep the polling going on. How can I achieve this?

This is what I have so far for the polling:

```
this.covidCases$ = timer(1, 60000).pipe(
      switchMap(() =>
        this.covidService.getCovidCases().pipe(
          map(data => {
            return data.cases;
          }),
        ),
      ),
      retry(),
      shareReplay(1),
    );

```

I then pass this observable to the component:

```
<case-list [covidCases]="covidCases$"></case-list>

```

Answer: 
you can try to change the URL from http to https

```
maven {
    url 'https://developer.huawei.com/repo/'
} // HUAWEI Maven repository

```
