I am using the same layer for six layers in this webmap: http://www.arcgis.com/home/item.html?id=a69b1cbde859433ba816ab0e036712b8.
I am getting a "not responding" error and only half of the layers are drawing properly. Any ideas why this is happening?
Use the ArcGIS Online Assistant - it allows you to modify the URLs for services in web maps https://ago-assistant.esri.com/
Select "I want to update the URL" from the top menu.
From the URL, click on Topo -> Basiskaarten/Topo (MapServer) and click on WMTS
In QGIS, choose Add Layer/ Add WMS Layer -> New and enter in URL https://services.arcgisonline.nl/arcgis/rest/services/Basiskaarten/Topo/MapServer/WMTS

This is an issue with the latest update to Chrome. This issue takes place when a second request is made to the same resource (your layers in the map). The browser does not handle this correctly and then you get the failures. An issue has been logged for Chrome, I currently do not know when the fix will be rolled out but can update this post when it does happen.
