If you are trying to connect via ssh from the same device, make sure you set
the port configuration of sshd to use a non standard one (greater than 1024,
eg: 22000).
You can do this by editing /etc/ssh/sshd_config and set Port 22000 (Replace
22000 with any non-standard port).
After this, you can ssh (from iSH itself) using ssh root@localhost -p 22000

History of Installation and Configuration of iSH Alpine Linux on my old iPhone 6 running iOS 12.5.7.
No external keyboard was available. The Apple external Bluetooth keyboard A1314 was not listed as a device on my iPhone 6.
The idea was to install and configure SSH and some other tools, so that I could log in to my iPhone from my iPad via SSH and have the possibility to use an external keyboard or from my Mac. This was just to learn a little bit more about SSH and Git.
Here are the step-by-step instructions, including the wrong steps that were taken.
