Can't open Node-red dashboard in HA, the password is not accepted

Hi, I am just starting up with node-red from Home Assistant. I have lights turning on and off from push-buttons via a raspberry Pi and Arduinos I have just got solar put on the house but it has a crappy, trend but I have an add on for Node for this app. I now want to start node-red dashboard but can’t get past :
Is it a port problem or what?
I use my login that lets me into Home Assistant
Help please, I think I am going mad.

your homeassistant user and password should work but if you installed the node-red addon from addon-store you should be able to access it via ingress. the node red icon should be on the left.
the link should look like this ip:port/a0d7b954_nodered.
