[keycloak-user] Error when session expired and ajax request execute in Keycloak?

Hi, can you help me! When session expired and ajax request execute in Keycloak, i have error in browser console: XMLHttpRequest cannot load http://dc09-apps-06:8090/auth/ realms/azovstal/protocol/openid-connect/auth?…ml&state= 60%2F01fc2e79-6fc0-46b8-9f83-39b7421fedf9&login=true&scope=openid. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. I add in Keycloak admin console, in the client setting, Web Origins= http://localhost:8080 (or *), and enabled cors in app, but still has error in console. I used Keycloak 2.5.0
