    <font size="+1">For the first time, I'm trying to use a map from
      Mapbox as a base map in QGIS.  I opened an account at Mapbox.com
      and made a map there using their "Satellite streets."    I clicked
      Publish and chose Publicly available.  I copied that map's Style
      URL and Access token and plugged them and my Mapbox username into
      what I believe is the correct endpoint template.  Then back at my
      desktop QGIS, I clicked  Layer > Add Layer >Add WMS/WMTS
      layer > new .  Then I entered a name and plugged in my custom
      endpoint URL.  Then I clicked OK and saw at the bottom "93546 of
      93546 bytes of capabilities downloaded."  Then I clicked Connect
      and got the following message:  "Failed to download capabilities".<br>
        I'd be grateful if someone will tell me what I'm doing wrong.   
      Thanks, Steve<br>
