EC2 instance ssh: connect to host ipaddr port 22: Operation timed out on MacOS
Hi there, new developer here!
I just signed up for my EC2 Windows2022 instance and would like to connect it from my Mac (M2, Sonoma14.5) terminal using SSH, but all trials failed with the error: "ssh: connect to host ipaddr port 22: Operation timed out".
Based on the previows posts regarding the same issue, I've tried a couple of things:
-
Add SSH Port22 into the security group rules, as well as ICMP protocols
-
Add SSH into ACL rules
-
Reboot and check the status of the instance (numerous times)
-
Ensure my IP is not a public one and tried different IPs to connect
-
Ensure I've turned on the remote login option
-
Turn off the firewall on my Mac
However, after tried these, I still fail to connect via SSH and been stuck here for several days. Would you have any more ideas. I'll appreciate though. Thank you!

This is going to be the source of at least one of your problems, your EC2 instance needs to have a public IP address and it is that public IP address that you need to connect to.
Just as importantly, Windows won't normally accept SSH connections (without some severe customisations). The normal way would be to use RDP over port 3389, which you already have opened.

Thank you for pointing that out and for these suggestions! I've checked my IP and it starts from "76", so it's a public addr now. I just tried again on my Mac Terminal using the command "ssh -i [key].pem ec2-user@[ec2 public DNS]", but it failed (same error). Any other things I need to check?
In your question you said:
This is your problem, you cannot SSH to a Windows instance.
Thank you all. That's exactly where the problem comes from. I can easily use RDP to connect. Appreciate!
