I was using Lightsail to deploy a simple discord bot, but my discord bot policy changed, so I haven't maintained it for a while (about a year) I tried accessing the instance because I wanted to save the discord bot for the first time in a while, but all the methods failed. Below are the methods I tried. 1. Access to webssh provided by Lightsail - Failed ![여기에 이미지 설명 입력](/media/postImages/original/IMDek8Ln9cRUiyt4kt4oXD1A) 2. Take the most recent snapshot and create a new instance - Failed 3. Access the IP directly from the browser - Failed I tried these three methods, but I couldn't access them all As far as I'm concerned, the instance itself is not running. I'd appreciate it if you could tell me how to solve it

There is no way to access the Lightsail instance, such as ssh, http, etc be not accessible by any means "UPSTREAM_NOT_FOUND [519]"

Are ssh and http packets allowed in the Lightsail firewall?
Also, do you get any error messages when you access the site?

Network settings are set to allow all ports. Also, when accessing with a browser, you cannot access the IP itself I corrected the error picture in the question

Thanks for the reply. The following document provides general troubleshooting instructions when that error message occurs. https://repost.aws/knowledge-center/lightsail-resolve-ssh-console-errors
Perhaps the SSH service is down. So, please set the following command in the launch script when restoring from a snapshot.

sudo ufw disable sudo iptables -F sudo mv /etc/hosts.deny /etc/hosts.deny_backup sudo touch /etc/hosts.deny sudo systemctl enable sshd sudo systemctl restart sshd

Please check the above document once for other troubleshooting methods.
