# Test Host Connectivity to Platform9 Cloud over SSL

## Problem

* Hosts connect to port 443 of Platform9 Cloud (Management Plane).
* Even though telnet, nmap or nc can be used to verify TCP connectivity to the cloud, it doesn't validate connectivity over SSL.

## Environment

* Platform9 Managed OpenStack - All Versions
* Platform9 Managed Kubernetes - All Versions

## Procedure

* To test SSL connectivity from the host to the management plane, run the command below after substituting the value to **\[MANAGEMENT\_PLANE\_FQDN].**

{% tabs %}
{% tab title="None" %}

```none
$ openssl s_client -connect <MANAGEMENT_PLANE_FQDN>:443 -servername http-v1 -cert /etc/pf9/certs/hostagent/cert.pem -key /etc/pf9/certs/hostagent/key.pem -CAfile /etc/pf9/certs/ca/cert.pem
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
**Note**

This won't work in environments using proxy servers to forward traffic.
{% endhint %}
