Hi,

Could you please tell me why after the access token expires, i cannot access the zuul resource.

I got the following error.

20:22:26.600 [qtp798874225-540] DEBUG o.s.s.w.a.ExceptionTranslationFilter: Authentication exception occurred; redirecting to authentication entry point
org.springframework.security.authentication.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext
	at org.springframework.security.access.intercept.AbstractSecurityInterceptor.credentialsNotFound(AbstractSecurityInterceptor.java:379)

I have to login again from google to regain access.

Thank you.
