@jyousefpour1 After small investigating the problem, I have identified the root cause and a potential solution.

The issue stems from the presence of the tag in the operator/web-app/public/index.html file. This tag forces all relative links and resource paths within the web application to be resolved from the site root /, instead of the path prefix where the Minio Operator is deployed when running behind a reverse proxy.

Hello jyousefpour1, thank you for raising this issue. I believe it is related to the following:

• Applying same console fix for the subpath issue #1616
• Fix Subpath behavior console#2818

The solution may lie within the environment variables of the console deployment for the operator:

apiVersion: apps/v1
kind: Deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/instance: minio-operator-console
      app.kubernetes.io/name: operator
  template:
    metadata:
      creationTimestamp: null
      labels:
        app.kubernetes.io/instance: minio-operator-console
        app.kubernetes.io/name: operator
    spec:
      containers:
        - name: operator
          image: docker.io/minio/operator:v5.0.4-13-g041a74ca
          args:
            - ui
            - '--certs-dir=/tmp/certs'
          ports:
            - name: http
              containerPort: 9090
              protocol: TCP
            - name: https
              containerPort: 9443
              protocol: TCP
          env:
            - name: OPERATOR_SUBPATH
              value: /minio-operator/

Particularly, in reference to this section:

          env:
            - name: OPERATOR_SUBPATH
              value: /minio-operator/

This can also be accomplished via the Helm chart, in the values file under the console section:

  ###
  # An array of environment variables to pass to the Operator Console deployment.
  # Pass an empty array to start Operator Console with defaults.
  env: [ ]
