We have been exposing public model views as IFrames in our Confluence documentation for some time but recently this has stopped working with "Connection refused". Using the link in a normal browser window still works fine. Example:
<iframe src="https://my.vertabelo.com/logical/public-model-view/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx?x=6500&y=6500&zoom=0.99" noborder="0" width="1500" height="1000" scrolling="yes" seamless></iframe>
Is there something that has changed in your request handling behaviour?
