Issue with LTI Integration: "Refused to frame due to Content Security Policy" Error

Hello everyone,

I am trying to implement LTI in Moodle to access a course from one Moodle instance to another. However, I’m encountering an issue where the course fails to load, and I receive the following error:

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

Has anyone experienced this issue before or know how to resolve it? I’ve checked my LTI setup, but I’m unsure if the problem lies with Moodle’s configuration or the Content Security Policy settings.

Any guidance or suggestions would be greatly appreciated.

Thanks in advance!
