Grafana config Oauth Keycloak but, not redirect to page login keycloak

Hi all, I config oauth keycloak,
Log from grafana:
evel=info msg=“Request Completed” method=GET path=/login/generic_oauth status=302 remote_addr=10.x.1x.x time_ms=0 duration=118.368µs size=249 referer= handler=/login/:name status_source=server
But form page login Oauth Grafana not redirect to page keycloak.
There is my grafana.ini file :
enabled = true
name = SSO_OAuth
allow_sign_up = true
client_id = grafana-oauth
client_secret = expASHIQNSAaasdashdasdnsadj
scopes = openid email profile groups
auth url =
token_url =
api url =
;skip_org_role_sync = true
;role_attribute_strict = true
;redirect_uri =
role_attribute_path = contains(realm_access.roles[], ‘grafana_admin’) && ‘Admin’ || contains(realm_access.roles[], ‘grafana_editor’) && ‘Editor’ || ‘Viewer’
