So I have set up a cluster with neo4j-helm chart, and configured SSL certificates with k8s cert manager.

I am passing the following configuration via the helm chart's configMap:

```auto
  NEO4J_dbms_ssl_policy_bolt_enabled: "true"
  NEO4J_dbms_connector_bolt_tls__level: "REQUIRED"
  NEO4J_dbms_ssl_policy_https_enabled: "true"
  NEO4J_dbms_connector_http_enabled: "false"
  NEO4J_dbms_connector_https_enabled: "true"

```

As of now, I am able to:

- connect cypher-shell using `neo4j+s://mydomain.com`; the `neo4j://` protocol doesn't work as expected
- open [https://mydomain.com:7473](https://mydomain.com:7473) in the browser. SSL certificate is valid there.

However, trying to connect to `neo4j+s://mydomain.com` using Neo4j Browser (either the standalone version or the one at mydomain:7473) results in the connection error:

```auto
WebSocket connection to 'wss://mydomain:7687/' failed: 

```

If I set `bolt.tls_level` to "OPTIONAL", I can connect via `neo4j://` with both the browser and cypher-shell.

Am I missing something? Appreciate any help or clues.

Can you check the advertised addresses?  
Perhaps browser tried to connect to the advertised address from the config?

You can check that with curl against the base URL 7474 or with call dbms.cluster.overview()
