I have an instance in AWS and I'm trying to connect to it via SSH I already try in Windows with Putty and PowerShell and I already convert the key pair to readeable format for Putty but it's not connecting to the instance the error says:
Connection Time Out
Also I already try to connect with a Linux machine but it doesn't work too
This is my instance configuration
These are my security group policy
Things to check:
Security Group permitting inbound access for port 22 (SSH) (Looks good!)
Network ACLs set to default (Looks good!)
Instance launched in public subnet (??)
Linux AMI used (Ubuntu, looks good!)
Instance has a public IP address (Looks good!)
The one thing that isn't clear is whether the instance was launched in a public subnet. This is defined as a subnet that has a Route Table pointing to an Internet Gateway.
If you can connect to other instances in the same subnet, then this would be configured fine. If you have not been able to connect to anything in the subnet, then check your Route Table configuration.

I'm trying to connect my friend's MySQL database remotely but I'm getting connection timeout error. I tried to ssh. But same result.
Then I check that instance. It has public IP. Also allowed 3306 and 22 ports on the security group. Allowed 100th rule for all sources in subnet NACL.
What I'm missing? Is there any other way to block those traffic? Can anyone help me? I'm a still beginner
When an SSH connection times-out, it is normally an indication that network traffic is not getting to the Amazon EC2 instance.
Things to check:
The instance is running Linux
The instance is launched in a public subnet, which is defined as having a Route Table entry to points to an Internet Gateway
The instance has a public IP address, which you are using for the connection
The Network Access Control Lists (NACLs) are set to their default "Allow All" values
A Security Group associated with the instance that permits inbound access on port 22 (SSH) either from your IP address, or from the Internet (0.0.0.0/0)
Your corporate network permits an outbound SSH connection (try alternate networks, eg home vs work vs tethered to your phone)

Based on your descriptions, I would suggest checking whether the instance was launched in a public subnet.
I found the reason. That instance was deployed in a private subnet and didn't have inbound access.
Solution:-
I deployed a bastion host in a public subnet and used SSH agent forwarding to access the instance through the bastion host.
I tried so many aws documentarian but not get output
when i go for connect to my EC2 console then i get this error
It would appear that you are attempting to connect to an Amazon EC2 instance by using EC2 Instance Connect.
Things to check:
The instance is running Linux
The instance is launched in a public subnet, which is defined as having a Route Table entry to points to an Internet Gateway
The instance has a public IP address, which you are using for the connection
The Network Access Control Lists (NACLs) are set to their default "Allow All" values
A Security Group associated with the instance that permits inbound access on port 22 (SSH) either from the IP range of the EC2 Instance Connect service, or from the whole Internet (0.0.0.0/0)
Your corporate network permits an outbound SSH connection (try alternate networks, eg home vs work vs tethered to your phone)
Given the information you have provided, I would suggest checking that the instance was launched in a Public Subnet.

I have tried all that I could have done.
Deleted the previous EC2 instances
Used a new key pair
Used putty to connect with new pair
Used chrome extension secure shell app to connect to EC2 instance with new key pair
I added my IP address in my security group inbound table but not able to access the EC2 instances.
Attached are the images of my issues.
Cause of the problem:
The port number for SSH is 22.
However, the screenshot for the ssh error shows that the connection is being attempted on port 80.
Suggested fix:
The problem can be fixed by specifying the port number as '22' in the SSH client connection settings.
To access the EC2 instance via SSH, check:
The instance has been launched in a public subnet (defined as having a Route Table that routes traffic to an Internet Gateway)
The Security Group should be permitting inbound traffic on port 22 from your IP address (or a wider range, such as 0.0.0.0/0)
Don't change the NACLs from default
Make sure the instance is running Linux
For EC2 Instance Connect, make sure it is using Amazon Linux 2 or Ubuntu 16.04 or later
Make sure you are connecting to the public IP address of the instance (based on your pictures, you are doing this)
Simple hint: If the connection takes a long time to fail (or hangs), then there is no network connectivity to the instance. Check Security Groups and VPC configurations. If an error comes back immediately, then network connectivity is okay and the connection is simply being refused by the instance.
Well, I am almost giving up on aws it is really hard to do simple things here. My problem is I am following this link to setup cpanel for commercial use,
https://blog.cpanel.com/part-2-how-i-built-a-cpanel-hosting-environment-on-amazon-aws/
I set up my VPC, Subnet, Internet Gateways, Elastic IPs and Route Tables and still can not connect to my ec2. it is frustrating that I am wasting time over an ssh problem which can be solved in a matter of seconds in OVH and here AWS ruining my day any ideas?
I set up my VPC, Subnet, Internet Gateways, Elastic IPs and Route Tables
I really expect to connect to my ec2 with ease and be able to add more ec2/s to the service
To be able to SSH into an Amazon EC2 instance, you'll need the following:
An Amazon VPC (the default one is fine, or create your own)
An Internet Gateway attached to the VPC (to connect it to the Internet)
A public subnet, which is defined as a subnet that has a route table where the route table sends traffic destined for 0.0.0.0/0 to the Internet Gateway
An Amazon EC2 instance in the public subnet, presumably a Linux instance since you want to SSH to it
When launching the instance, nominate a Keypair. If you launch from an Amazon-provided AMI (eg Amazon Linux 2), the keypair will be copied to /users/ec2-user/.ssh/authorized_keys at startup.
The instance should either be launched with Auto-assign Public IP to receive a random public IP address, or associate the instance with an Elastic IP address to associate a static IP address
A security group attached to the EC2 instance permitting inbound SSH access (port 22) either from 0.0.0.0/0 or your own IP address
Don't play with the Network Access Control List (NACL) settings - they default to allowing all traffic in/out
To connect to the instance:
ssh -i YOUR-KEYPAIR.pem ec2-user#IP-ADDRESS
If the connection is immediately rejected, it suggests a problem with the keypair.
If the connection takes some time before failing, it suggests a network-related problem because it is unable to contact the instance. Some corporate networks block outbound SSH access, so try again from a different network (home vs office, or even tethered via your phone) to try and identify the issue.
I'm creating a new instance by using the following command,
ec2-run-instances --key "xxxx keypair" --instance-type t1.micro --instance-initiated-shutdown-behavior terminate --user-data-file myscript.sh $ami_id
And my AMI is bitnami default AMI
after I launch the instance, used the following code from my older instance to connect new instance,
ssh -i xxx_yyy.pem bitnami#xxxxxx.compute-1.amazonaws.com
And I can't connect this, there is no response from server,
Can anyone please help me in this??
Thanks in advance.
Typical things to check when trying to connect to an EC2 instance:
Security Groups
Check that at least one of the Security Groups associated with the instance has port 22 (SSH) or port 3389 (RDP) open to your source IP range (eg a specific IP address 54.87.23.11/32, or the whole world 0.0.0.0/0 -- but the latter is very poor security practice). Security Groups are stateful, so you only need to open Inbound access and the return path will automatically work.
Public IP Address
Confirm that you are using a Public IP address associated with the instance. This can either be assigned at instance launch (which will allocate a random IP address from a pool) or can be assigned as an Elastic IP Address (which is a static IP address that you can assign assign to any instance and you keep it until you release it back to AWS).
Public Subnet / Routing
Confirm that your instance is in a "Public" VPC Subnet. This means that the Route Table associated with the Subnet has a route through an Internet Gateway.
AMI Operating System
I've seen situations where people try to SSH to a Windows instance, or RDP to a Linux instance, so also check that you launched the correct AMI for your expected operating system.
