I deployed the Neo4j Docker image on Openshift.

This is my deployment:

    spec:
      volumes:
        - name: neo4j-data
          persistentVolumeClaim:
            claimName: neo4j
      containers:
        - resources: {}
          terminationMessagePath: /dev/termination-log
          name: neo4j
          env:
            - name: NEO4J_AUTH
              value: neo4j/12345678
            - name: NEO4J_ACCEPT_LICENSE_AGREEMENT
              value: 'yes'
            - name: NEO4J_server_config_strict__validation_enabled
              value: 'false'
            - name: SERVICE.PORT.BOLT
              value: '7687'
            - name: dbms.connector.bolt.advertised_address
              value: '0.0.0.0:7687'
            - name: dbms.connector.bolt.listen_address
              value: '0.0.0.0:7687'
            - name: dbms.connector.bolt.enabled
              value: 'true'
            - name: dbms.connector.bolt.tls_level
              value: OPTIONAL
          ports:
            - containerPort: 7474
              protocol: TCP
            - containerPort: 7687
              protocol: TCP
          imagePullPolicy: Always
          volumeMounts:
            - name: neo4j-data
              mountPath: /data
          terminationMessagePolicy: File
          image: 'neo4j:latest'
      restartPolicy: Always
      terminationGracePeriodSeconds: 30
      dnsPolicy: ClusterFirst
      securityContext: {}
      schedulerName: default-scheduler

The service with ports 7474 and 7687 is okay. I generated two routes for each port. When I try to access using bolt://route:7687, I get this error: WebSocket connection to ‘ws:/’ failed: WebSocket is closed before the connection is established.
I also tried using neo4j://.

Any ideas how to fix that?
Thanks
