I’m having problems authenticating my system. I’m using Grails 3 with Springsecurity and when I will scale to 2 or more replicas in my Kubernetes cluster authentication stops working.
What I might notice is that the request is returning me one Status Code: 302 after performing the authentication, but I can’t find out the reason for the problem.
Note: I have another Rest application Grails 3 using Springsecurity with JWT authentication that works properly when scaling the application to more than 1 replica, I imagine that because every request needs to pass the Authorization Token and no application session is maintained.
