open url in iframe

[overstartup]

I need to open external url in my project by iframe. but i get this error:

Refused to frame 'https://www.w3schools.com/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self' https://mycourses.w3schools.com".

how can i solve this issue?

You can't ! If owning website server (here www.w3schools.com ) has explicitly denied do that by having frame-ancestors 'self'

[overstartup]

it should be none?
frame-ancestors 'none'
