SSH back to AWS Lightsail after UFW enabling

Question

I've enabled the UFW service without allowing SSH access before then logging off.

I am now unable to ssh back to the instance.

The steps I have already taken:

• Made a snapshot and create a new instance from it

Answer 1

The general point: try to execute a command (firewall disabling) while creating a new instance. I was able to do it with the usage of AWS CLI:

aws lightsail create-instances-from-snapshot --region eu-central-1 --instance-snapshot-name TEST_SSH_FIX-1591429003 --instance-names TEST_SSH_FIX_2 --availability-zone eu-central-1a --user-data 'sudo service ufw stop' --bundle-id nano_2_0

It`s work.
