Lightsail Instance SSH Connection not build into Mac terminal : Error ssh: connect to host 172.26.13.112 port 22: Operation timed out

Question

Hi 👋 Folks,

I am using Macbook M2 Pro Terminal to get connect with my light sail instance, unfortunately, it gives an error on terminal which is underfollowing

ssh: connect to host (Lightsail instance Ip  port 22): Operation timed out

However, I have provided all details including proper parameters as defined by Amazon Articles with absolute path    like  
 ssh -i /Users/amirali/Desktop/SecurityKeysFile/xyz.pem root@IPaddress

that's how I give path as per file is save in above location. On other hand, I have follow the this Amazon article https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-ssh-using-terminal#terminal-ssh-change-key-file-permissions

Unfortunately, it's been more than 2 days unable to resolve, get stuck therefore, my all work is In complete

However, I am familiar with Linux therefore, I just need small assistance to get this work done.

What I have found through systemctl status sshd

Accepted Answer

From timeout error it look like there is some issue with network config or firewall.

Can you check the 22 port is filtered?

$ nmap  -Pn -p 80

If it is filtered check the firewall settings https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-editing-firewall-rules

I am facing the same issue, after creating multiple instances in lightsails, after using it for 30min to 2hrs, my ssh automatically gets shutdown & if I again try to connect, it always says "Opertaion timeout"

Looks like there is some issue in Lightsail Ubuntu instances.

Even if I try clicking on "connect using SSH" button on instance, a popup opens, but we cannot do anything, as nothing shows up or even cannot type anything.

Answer

Finally Figured out the issue, by creating another instance & was trying to replicate my issue that is: **"ssh: connect to host x.x.x.x port 22: Operation timed out"**. on my lightsail instance.

Why I am unable to connect to the instance via SSH is that I did turn on the UFW in my ubuntu instance by typing `sudo ufw enable`, that is the main mistake I made, after doing this when I tried to connect my instance again via same steps, I was unable to connect.

**The solution is, whenever we turn on the ufw, we must allow ufw with port 22, by running the command `sudo ufw allow 22`**
