I had created an Amazon EC2 instance and was able to SSH into it previously. Now if I try to SSH into it, I get the error as below:
ssh: connect to host [ip address] port 22: Connection timed out
I've not changed anything in the security group and NACL to which the instance and the subnet are attached respectively.
Creating another instance from the AMI of this instance doesn't seem to work either.
I tried fixing the problem by detaching the EBS volume from this instance and mounting it to a fresh instance for checking /etc/ssh/sshd_config, but there wasn't any problem there.
I've also tried commenting out stuff from the fstab as per the solution https://stackoverflow.com/a/14050894
I'm facing the same issue in around 3 instances, kindly help.
Below is the output of ssh -v
