Installation Error [SOLVED]

Hello all, i have trying to install Ghost from official documentation guide.
I deploy it with aws lightsail instance, but its not working correctly.
If i visit my custom domain its looping in connection.
Mysql : 5.7 (aws rds)
OS : ubuntu 20.04
NodeJs : 12.x
Webserver : Nginx

I have fixed this issue, because i forget to allow traffic from incoming port 443 https
