Leaflet Map not rendering in Rmarkdown, R Notebook when opened in browser

For some reason, I can view the leaflet map in the RStudio viewer, but not in a browser, even a very basic map.

```{r, echo=FALSE, warning=FALSE}
library(leaflet)
m <- leaflet() %>% addTiles()
m
```

All other images appear no problem when viewing the HTML file in the browser, but the map won't. Does anybody ran into this problem before?

Just open the map in Browser instead of Viewer. The same with shiny.

Reposting from GIS stack exchange, which worked for me:

"The solution is simply reminding leaflet what the basemap is. It defaults to OSM in RStudio output, but then didn't export it with html."

I added (repeated) the following code at the end of the all my leaflet code.

%>% addProviderTiles(providers$CartoDB.Positron)

There is something wrong with the default tiles set. Try this:

```{r, echo=FALSE, warning=FALSE}
library(leaflet)
m <- leaflet() %>% addTiles(urlTemplate = 'http://{s}.basemaps.cartocdn.com/dark_all/{z}/{x}/{y}.png')
m
```

You can find a good resource here for alternative third-party tiles.
