Hi, im trying to embed my app in a wordpress website, im using an iframe (i know it is not the best option, but still want to try it). In the sample page i add this [advanced_iframe src="https://thewebtoolboxhub.pythonanywhere.com/"] if i preview i get this my-app.pythonanywhere.com refused to connect. with a :( smiley on top. Any idea how i can fix this? thanks!
