If the token expires Node-Red will stop talking to Home Assistant. You need to create a new token. First click on my photo icon at the bottom left of the HA page.
Then create a new long lived access token. Copy the token into notepad++ as it will dissapear from view after creatioon.
Next go into node-red and click on any home assistant link, you only need to do this once. Click on the blue connector. This open the main dialogue.
Then click on the pencil to the right of server Home assistant
Then enter the URL and new token into the dialogue box.
