<p>We have microservice with identity server 4. When user login to the app, and we restart pod with this microservice, then somehow token is still valid (user can browse app) but when he click logout then there is call to endsession which removes the token and redirection to logout page (but since there is no token we get access denied )</p>

<p>Since you're not properly persisting your persisted grants, signing credentials and data protection keys then you will get all sorts of odd behavior when you scale across multiple processes or restart an instance. You must address these considerations before deploying into this sort of environment.</p>

<p>I suspect in your example the cookie issued to the user is no longer valid as the data protection keys used to encrypt and sign said cookie will no longer exist.</p>

<p>See the following documentation:</p>
