Hello guys, I am trying to fix this for 4 hours now so I really hope you can help me...
I am using keycloak as an Identity Provider to acces my editor.
I modified my settings.js file as described in this post [here](https://discourse.nodered.org/t/oauth-openid-login-with-keycloak/54144).
```auto
adminAuth: {
type: "strategy",
strategy: {
name: "keycloak",
label: 'Sign in',
icon: "fa-lock",
strategy: require("passport-keycloak-oauth2-oidc").Strategy,
options: {
clientID: "account",
realm: 'master',
publicClient: "false",
clientSecret: "deleted",
sslRequired: "none",
authServerURL: "http://localhost:8080/auth",
callbackURL: "http://localhost:1881/auth/strategy/callback",
verify: function (token, tokenSecret, profile, done) {
done(null, profile);
}
},
},
users: [
{ username: "user", permissions: ["*"] }
]
},
```
My keycloak configurations are:
Realm name: master
Client config:
When I go to my app on localhost:8080 and click Sign in I get the following error:
What I am doing wrong, I tried multiple changing the authServerURL and callbackURL 100 times but no success.
Thank you!

Have you installed `passport` and `passport-keycloak-oauth2-oidc` using npm?
You may need to show the entire error message that is in that box - there are probably clues there.
I don't think it's even reaching out to Keycloak but I will also note that master realm is not recommended to use for anything but Keycloak administration, and I would definitely recommend to create a Client specifically for Node-RED so that you're not re-using credentials for different services and you can provide the specific redirect URI that you need to allow.

Yes, I have installed them with npm.
The error:
Node-RED

URL Decoded...
```auto
InternalOAuthError: Failed to obtain access token (status: 404 data:
Not Found
Access Error: 404 -- Not Found
Cannot open document for: /auth/realms/master/protocol/openid-connect/token
)
```
Does that help?
