Shopify non-embaded to embaded convert issue Refused to display iframe

[helpy]

Hello All,

I am facing an issue while opening the shopify app with embedded to admin. However, it's working fine without being embedded. But when I enabled shopify embedded admin at that time I faced the issue.

I already added 

Content Security Policies "frame-ancestors https://[store].myshopify.com https://admin.shopify.com;"

 My app is hosted on the NGINX server. Please let me know how I can resolve it.

Thanka
