Can't connect to instance after enabling ufw verbose

Question

I enabled ufw verbose that closed all ports, so i think i can't connect ssh to my instance due to ufw, now i can't connect to my instance using nor lightsail ssh console nor my own windows console. Tried to snapshot and create a new instance, but i think ufw settings also inherited so i can't connect to new instance either. What to do?

Accepted Answer

Hi,

You could try injecting commands in the launch-script while creating a new instance from the snapshot to potentially recover access to the instance.

For inspiration an example can be seen [here](https://repost.aws/questions/QUytlu4EZgTjuiKhWPF_IE4w/change-rdp-port-in-lightsail-server-and-now-no-connection#ANQeMAvGfPS429t30QkT5RqQ)

Thanks.

Hi

1. Access via Lightsail console (if available): Lighsail offers a console access option. This might be available through the web interface and could allow you to access the instance directly bypassing SSH. Once logged in, you can disable ufw.
2. Stop the instance and add user data script to disble the UFW. [Example](https://docs.aws.amazon.com/lightsail/latest/userguide/lightsail-how-to-configure-server-additional-data-shell-script.html#example-configure-ubuntu-using-apt-get-install-node-js)

```
sudo ufw disable
```
3.use snapshot restore [Click the link for the steps](https://www.seahorse-data.com/how-to-restore-aws-wordpress-lightsail-instances/)
