My website is loading some images from ip instead of domain - AWS Lightsail

Have you specified your domain in the General settings? You must explicitly configure the "WordPress Address (URL)" https://wordpress.org/documentation/article/settings-general-screen/ for your domain to apply to your media assets.

By default, you can point a DNS record to the server and see your site in the URL, but you need to explicitly configure it for your domain to apply everywhere.

General settings are properly updated too. But still the static IP is regenerating issue and corrupt images.

Once we set up the Cert through the LightSail console, we should not have to do anything. There is an issue with Wordpress on LightSail that is documented here on Rededit. We should be able to use Elementor without issue.

Hello.

AWS re:Post is a community forum site, so we can give you advice, but you must make your own corrections.
If you are using Wordpress, please make sure that your Site URL or WordPress address has been correctly changed to your domain.

I did a little research and found that there is a plugin for rewriting URLs, so please consider using that.
