I have created an ec2 instance and set the security group such that it is open for all ip but when i try to access the instance via public ip or dns i get the following error :
This site can’t be reached
ec2-xx-xxx-xx-xx.ap-northeast-1.compute.amazonaws.com refused to connect.

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 have an ec2 instance running ubuntu and im trying to restrict ssh access to only my ip address, im using both the security on the ec2 and the network acl, i have multiple ip addresses
192.168.1.233: the one on my computer in system prefrences -> network under the name of the wifi network
157.100.197.222/32: the one in the ec2 when i edit inbound rules under the option my ip address https://i.stack.imgur.com/WXCxh.png
172.31.30.243: the one when i connect to the ec2 and type hostname -I | awk '{print $1}' https://i.stack.imgur.com/oHuc5.png
im able to connect to the ec2 when in the network acl inbound rules i deny ssh acces to /8, /16, and /24 and then allow all other sources and in the security of the ec2 i allow all sources to connect via ssh https://i.stack.imgur.com/zOuhS.png https://i.stack.imgur.com/tOkcL.png
but right now im allowing access from all 3 of my ip addresses and denying everything else and it wont connect https://i.stack.imgur.com/AnyVI.png https://i.stack.imgur.com/RM3YA.png
i know it has something to do with the network ip address vs the device ip address and using the right ip with the right cidr block but i dont know exactly what to put, can someone help me
You have to check what is your outgoing IP address. You do this by going to any "check my ip" website. This will be the address you have to allow in your security groups.
Also do not modify network ACL. Default NACL is all that you need. Only use Security Groups to control access to your instance from your IP.
The error message appears to indicate that you are attempting to connect to the Amazon EC2 instance by using EC2 Instance Connect.
EC2 Instance Connect works as follow:
It uses a web connection (port 443) from your browser to the EC2 Instance Connect service
The EC2 Instance Connect service then establishes an SSH connection (port 22) from the EC2 Instance Connect service to your Amazon EC2 instance
Therefore, the Security Group sees your connection as coming from the EC2 Instance Connect service rather than the public IP address of your computer.
You would need to add the IP address ranges of the EC2 Instance Connect service the Security Group to permit access to the EC2 instance (see Set up EC2 Instance Connect - Amazon Elastic Compute Cloud). However, this would permit an inbound connection from any computer that successfully authenticates via the EC2 Instance Connect service.
Thus, it is not possible to restrict access to the EC2 Instance to your own IP address while using EC2 Instance Connect to connect to the instance.
However, it is worth noting that EC2 Instance Connect uses IAM to authenticate access to the instance, so you should trust this authentication. Rather that restricting by IP address of computers, you could restrict to the IP address ranges of the EC2 Instance Connect service and then use IAM permissions to control access to the instance.

It would appear that you are attempting to connect to an Amazon EC2 instance by using EC2 Instance Connect.

Given the information you have provided, I would suggest checking that the instance was launched in a Public Subnet.

My Setup,
i added my ip address in inbound rules of security group
access key is connected properly to ec2 and locally i given enough permission to the key while ssh
i saw the ec2 instance connected to public subnet
public subnet is connect to internet gateway which opens the path to internet
Important Notes:
if i set the inbound rules to 0.0.0.0 in security group i can able to ssh into my instance but not able to ssh with my ip address
i checked my indian friends and added their ip address interesting part is they can able to access
Can someone help me where is the restriction comes i tried all my possibilities not able to fix this
I'm trying to connect to my AWS RDS Instance but i keep getting this error :
The public access is already set to public :
As per snapshot, it throws connection timeout. Check your security group for inbound connectivity for 3306 port.
