Getting "Invalid parameter: redirect_uri" trying NODE.JS authentication with KeyCloak

I guess you added a port to your client URLs in your client settings tab.

e.g.

root url: https://demo.server.biz:443/cxf

just remove the port

root url: https://demo.server.biz/cxf

the same goes for Valid Redirect URIs and Web Origins
