Forbidden error when embedding shiny app

When trying to access a shiny app embedded into my personal page, I get a "Forbidden You don't have permission to access this resource". error. The app is located on a local shiny server ( open source version) and the app works great if I put the address directly into the browser. The shiny server is on a local machine and I'm developing and testing my pages using Xampp.

As already commented on your crosspost: You will need to check the X-Frame-Options of your shiny-server.conf.

There is no X-Frame-Options set in the shiny-server.conf so by default it should be allowed right ?

my bad. I orginally had https:// in my link and as that was not working I removed the HTTPs totaly.
Once I put back http:// instead of https:// it worked. Thank you.
