I am trying to connect the AWS RDS Instance on a local machine using Datagrip. The RDS instance have public access and inbound traffic is allowed from my IP address + all traffic is allowed for testing, but keep getting connection error. Screenshots are attached below, not sure what's causing this.

I'm working with AWS, I have an EC2 instance (Amazon Linux) but I can't connect to it, I've checked all VPC parameters and they are enabled as well as the instance, but when I try to connect it using EC2 Instance Connect I get this message:
I'm using the default user account, also I generated a key pair however I'm getting this other message:
Also, session manager can't connect.
So my question is: what settings do I need to update or check in order to connect to my EC2 instance?
Thanks a lot for your comments.
There are multiple ways to login to an Amazon EC2 instance.
SSH
Your screenshot shows that you are wanting to login via SSH, but it is saying that no Keypair was selected when the instance was launched. Therefore, this option is not available for you.
EC2 Instance Connect
If you ware wanting to login to the Amazon EC2 instance using EC2 Instance Connect and you are experiencing connectivity problems, then make sure that your Security Group permits Inbound access on port 22 from the IP address range of the EC2 Instance Connect service (not your own IP address).
This is because the EC2 Instance Connect client on your computer connects to AWS on port 443 (as a web connection), and then the traffic goes from the EC2 Instance Connect service to the EC2 instance as a normal SSH connection on port 22. Therefore, the Security Group needs to permit Inbound connections on port 22 from the IP address range of the EC2 Instance Connect service (or you can be lazy and just select 0.0.0.0/0, but that is a lower level of security).
You can find the IP address ranges for AWS services at: AWS IP address ranges - AWS General Reference
Please note that your EC2 instance must be in a public subnet and you must connect via a public IP address.
AWS Systems Manager Session Manager
The Session Manager connects in a totally different way, without using SSH. It requires an Agent to be installed on the EC2 instance (and it is there by default if you launched from an Amazon Linux AMI). This Agent then creates an Outbound connection to AWS, so it does not require any Inbound security rules (but it does require the default "Allow All" Outbound rule).
Session Manager has the additional benefit that it allows you to connect to EC2 instances that are in private subnets, as long as the EC2 instance can access the Internet via a NAT Gateway or if the VPC has a VPC endpoint for Systems Manager.
I am working on my bachelor thesis which involves creating a lab environment for the Introduction to cloud computing subject.
Recently found out that there was 1 extra VPC in the landing zone, decided to delete it in case someone accidentally chooses it and they have problems. Turns out I had been using that same VPC to test labs and now I cant connect to a EC2 instance old or new through ssh or aws connect even with the root account using the default Control Tower VPC.
First guess was that the internet gateway was configured poorly but adding a gateway did not solve the problem.
Has anybody had the same issue ?
To be able to connect to an EC2 instance via SSH over the internet, you must make sure that all of the following conditions are met, regardless of whether you provision the AWS account and the VPC via AWS Control Tower or any other means:
at least one of the security groups attached to the Elastic Network Interface (ENI) assigned to the instance to which you establish the connection must have an inbound rule for SSH to allow from the originating host (you).
the ENI must have a public IP address assigned to it.
the subnet the EC2 instance is deployed in must have an ALLOW rule for incoming and outgoing IP packets sent/received from SSH (this will be the case for a subnet in the default VPC).
you must have an internet gateway in your VPC.
the route table of the subnet the EC2 instance is deployed in must have an entry for the internet gateway.
for SSH connection directly from your computer, you must be in posession of the private SSH key with which you initiate the connection and the EC2 instance must have been configured to use the corresponding key.
I have created RDS instance with my own VPC. I had selected public accessible while creating the RDS instance. I have attached internet gateway with VPC. The security group for RDS has entry for 3306 port with my system IP address. I am using default ACL. Still on connecting the RDS instance from mysqlworkench error is coming.
Double check that you have added to correct information and test connection from above
image. You also need to open 3306 port for your instance. Check if
you have root user privileges in console.
I have a AWS RDS instance (PSQL), which is public accessible. For testing I attached a Security group that has on port 5432 all access 0.0.0.0/0. My VPC has a Internet Gateway attached and has the following
192.168.0.0/16 local
0.0.0.0/0 igw-0f41c33417cbccb8c
If I try to connect to the instance I get a network timeout and it seems my request is blocked.
But I dont find anything else that should block the connection
If it helps the VPC and the subnets are default and created for eksctl the major adaption I made was attaching a Internet Gateway
From inside the VPC I can access the RDS instance from outside (eg my local machine I can't)
I'm new and trying to explore AWS and creating a test app running on IIS (EC2 set in Public) and MSSQL RDS(set in Private). However my IIS is not able to connect on the RDS. Looking on my IIS EC2 it has a defined private IP too, same subnet used also from RDS, security group of RDS allows the subnet of the EC2, IAM of EC2 also has RDS Full access.
But still my ec2 wont connect on the RDS. May I ask on what I'm missing on my settings?
It appears that your configuration is:
One VPC
A Public Subnet containing an Amazon EC2 instance
A Private Subnet containing an Amazon RDS for SQL Server instance
You are attempting to connect from the EC2 instance to the RDS db instance
For this to work, you should configure:
A Security Group (let's call it EC2-SG) that is associated with the EC2 instance, permitting connections such that you can login to the EC2 instance
A Security Group (RDS-SG) associated with the RDS db instance, with an incoming connection configured for SQL Server (port 1433) with source set to EC2-SG
That is, the database security group should ALLOW an incoming connection with a source of the security group that is associated to the EC2 instance. The VPC will automatically figure out the IP addresses — you do not need to specify them.
Then, connect from the EC2 instance to the RDS db instance via the DNS Name of the RDS instance that is given in the RDS console.
