RHSSO - Error with Refresh token

Unable to refresh token in springboot application, getting ERROR RefreshableKeycloakSecurityContext:147 -Refresh token failure status: 400 {“error”:“invalid_grant”,“error_description”:“Token is not active”}.

SSO Session Idle : 15min
SSO Session Max: 8hr
Access Token Lifespan: 5 min
Access Token Lifespan For Implicit Flow: 5min

Any help will be appreciated !

Thanks in advance.

The Implicit Flow doesn’t support refresh tokens (RFC-6749). In case you have implemented it.
