Please excuse my ignorance as I am very new to the Node red and Raspberry pi's in general.
I can ping google.com so I know that I am connected to the internet.
The error the I am getting is as follows:
npm ERR! Error while executing:
npm ERR! /usr/bin/git ls-remote -h -t ssh://firstname.lastname@example.org/node-red/node-red-dashboard.git
npm ERR! ssh: connect to host github.com port 22: No route to host
npm ERR! fatal: Could not read from remote repository.
npm ERR! Please make sure you have the correct access rights
npm ERR! and the repository exists.
npm ERR! exited with error code: 128
npm ERR! A complete log of this run can be found in:

That isn't the address I posted - it was 220.127.116.11
However, assuming that is a mistype in your post rather than when you ran the command it is most likely a firewall somewhere. Can you access github from another machine on the same network? You can go to github.com in a browser. How about on your mobile network if you have one.
