I was doing this lab https://awsacademy.instructure.com/courses/85814/modules/items/7803186 yesterday, then I already finished setting up all the EC2, RDS, Cloud9 environment and etc.
I was able to perform the operation (CRUD) on the website, and also performed load test for the website. However, today, I started the lab, I wanted to try out the website again, then I found out the website could not load the data from the database, it supposed to show a list of students on the Student List section. So, I thought it was the mysql database issue, so I try logging in, which I found out that the data is still accessible, just that the website is unable to display the data.

I would appreciate if anyone could guide me on this

I am trying to access my private rds instance from my local machine so that I can view its data using gui tools. I have read you can use a ec2 instance as a bastion host to access. For my application setup, I am using an ec2 instance for my backend which is already in the same VPC as my rds and I have set up the proper security group.

In my EC2 aws rds describe-db-instances --region eu-west-1 just hangs, while aws ec2 describe-instances works, for example.

I recently began exploring AWS services and have been experimenting with EC2 and RDS within its free tier.
