Unable to login into UI with multiple replica count

[micrOsman]

Hello all,

I have trouble regarding multiple Kafka-UI replica counts. I'm not able to login into Kafka UI when more than 1 replica count is set. The authentication method is Basic Authentication - username+password. When I fill in the correct credentials login page just reload and no action happens. No events in pod logs are visible. Do you have any idea?

Thank you.

App version: v0.7.0

Kafka-UI helm config:

I was running into this same issue with my setup and was able to fix by enabling sticky sessions with the ingress deployed with application example

Essentially just need to add the following annotations to your ingress:
nginx.ingress.kubernetes.io/affinity: "cookie"
nginx.ingress.kubernetes.io/session-cookie-name: "route"
nginx.ingress.kubernetes.io/session-cookie-expires: "172800"
nginx.ingress.kubernetes.io/session-cookie-max-age: "172800"
