Quick sight Embedding error in London Region

I have created an Html page in an s3 bucket and made the bucket public. when I tried embedding the quicksight dashboard in the Virginia region, it all works seamlessly. But the same thing when I created the s3 bucket, API gateway, and lambda in the London region, I am getting the below error in the iframe. Refused to frame 'https://eu-west-2.quicksight.aws.amazon.com/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors

Can anyone assist me with this?
