Hi Timo I tried implementing the same solution in my Oracle APEX environment, but I’m facing an issue where the embedded page does not load and instead shows a “refused to connect” error from the Oracle Cloud APEX URL.

Both applications are in the same workspace, and I’ve enabled session sharing as described. However, the iframe still fails to load the target page.

I wanted to check with you:

Are there any additional security settings (CSP / X-Frame-Options / instance-level settings) that need to be adjusted?

Does this solution depend on a specific APEX version or hosting setup?

Are there known limitations when running on Oracle Autonomous DB / ORDS Cloud?

Any guidance or clarification would be really helpful.

Thanks for sharing such a useful article, and I appreciate your time.

Best regards, Minu
