I found Why are the Google basemaps no longer appearing in QGIS? which explains a simple method to reach the google tile server and get the Google Physical tiles. Has anyone a similar code with which I can get the Google Streets tiles? I'm unfortunately not really into programming and just a user of QGIS which is why I have to ask this question.
I'm using QGIS 2.14.8 and I'm unfortunately not able to upgrade right now. So using XYZ tiles or QuickMapServices is not possible. I am using OpenLayers plugin but this one is way too often not working the way I'd like it to work.
