Uncaught SecurityError: Blocked a frame with origin "https://localhost:44300" from accessing a frame with origin "https://othersite". Protocols, domains, and ports must match.
As you can see, both sites are https.
I am trying to access the properties of an iframe that is within my website. Could any one push me in the right direction?
If you can't make sure that both sites run on exactly the same protocol, domain and port, you might think about using a proxy solution with your webserver.
Depending on the browsers and versions you need to support, you can choose CORS to solve the problem.
