504 Gateway Time-out on AWS

I got a situation that when I restrict the IP by Security Group on AWS only my company's IP, which that only access to WordPress website from my own. But, when I do that I can't access my WordPress website.
I use Route 53 for domain, CloudFront CDN, ALB and EC2 instances install aaPanel behind.

Whereas, When I configure security group public port 80, I can reach my WordPress website normally.

Hello, after the website uses CDN, the ip that accesses the website will not be the real ip of the customer. It will be the ip of the CDN.
The real client ip can be displayed according to the tutorial settings of CloudFront CDN

Additionally, I still access aaPanel normally
