Browser is not allowed to display embedded content in popup

[GeoinformationGießen]

Hi,

I want to use this WMS in a web map containing several electric charging stations: https://sg.geodatenzentrum.de/wms_bnetza_eladesaeulen

For that usecase it is crucial to have pop-ups enabled so users can get more information about the charging stations. When activating pop-ups and clicking on a feature, the pop-up opens, but it says that the browser (in my case firefox, but with edge it is the same problem) is not allowed to display the content because it is embedded. I can open the content in a new tab and there I get the right information, but that is not how it should work. The information should be displayed in the pop-up.

What can I do to "allow" the display of the content?

Here is my sample map: https://giessen.maps.arcgis.com/home/webmap/viewer.html?webmap=b85fafa3d0954621a13e6edb7ca2cef0

Hi @GeoinformationGießen the pop-ups can be enabled/disabled, as you can see in the documentation here https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-support-WMSSublayer.html#p...
However the content itself comes from the service so there might be something wrong with the service itself. Are you able to contact the owner of the WMS?
