Did you try ssh to your Ubuntu server and receive the “ssh: connect to host port 22: Connection refused” error? This is likely because you need to enable SSH on the Ubuntu server.
The steps covered in this guide are for Ubuntu 22.04.3. If your server is a different version, I cannot guarantee that it will work.
Step 1: Install OpenSSH Server
You need a tool to process the request to ssh to your server. The OpenSSH Server allows you to ssh to your server remotely.
The first step to enabling ssh on Ubuntu is to install the OpenSSH Server.
