SSL certificate not valid on EC2

Question

I'm trying to configure SSL for my domain by the instruction given by this article ref:    . Now after doing these steps it always showing "Site's security certificate is not trusted." How can I solve this by making the certificate trusted for all user accessing the website.

You have a valid SSL certificate. However, because it is a self signed certificate (created by yourself and not by Certificate Authority) browsers don't trust it.   
  
You have two free options:  
1) Create an Elastic Load Balancer and add a Certificate created by AWS Certificate Manager (please refer to https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html)  
2) Use a free certificate from a CA like Let's Encrypt. It is very straightforward to set up. (please refer to https://letsencrypt.org/getting-started/)  
  
Hope that helps.

Let's Encrypt led me to the right answer thanks.

Since LightSail uses Bitnami, here is what I needed to use:
https://docs.bitnami.com/general/how-to/generate-install-lets-encrypt-ssl/

From the Console, just type:
sudo /opt/bitnami/bncert-tool
And then follow the prompts.

Thanks!
