Hi @SvenW ,
From my test, it works as below.
Normally, it will not prohibit Power BI from opening a webpage. I wonder that "not working" you said meant after you clicked the button, nothing happened, or after you clicked the button, it junped to website but couldn't open the webpage as below.
You can try another web url or create a web text box to see if you can open the website. Or you can try to refresh or update your Power BI Desktop.
