I am using Identity server 4 on kubernetes as a DaemonSet , now in my cluster i have 4 node , so there is 4 instance of that DaemonSet . my problem is that when i try to refresh a token sometimes it work and in other cases the server return 401. I added PersistKeysToStackExchangeRedis package to persist DataProtection on redis but the problem is not solved. Is there any solution please.
