| <p>This section describes how to prevent or resolve issues related to network policies. |
| Che requires the availability of the WebSocket Secure (WSS) connections. |
| Secure WebSocket connections improve confidentiality and also reliability because they reduce the risk of interference by bad proxies.</p> |
| </div> |
| <div class="ulist"> |
| <div class="title">Prerequisites</div> |
| <ul> |
| <li> |
| <p>The WebSocket Secure (WSS) connections on port 443 must be available on the network. Firewall and proxy may need additional configuration.</p> |
| </li> |
| <li> |
| <p>Use a supported web browser:</p> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Google Chrome</p> |
| </li> |
| <li> |
| <p>Mozilla Firefox</p> |
| </li> |
| </ul> |
| </div> |
| </li> |
| </ul> |
| </div> |
| <div class="olist arabic"> |
| <div class="title">Procedure</div> |
| <ol class="arabic"> |
| <li> |
| <p>Verify the browser supports the WebSocket protocol. See: <a href="https://www.google.com/search?q=websocket+test">Searching a websocket test</a>.</p> |
| </li> |
| <li> |
| <p>Verify firewalls settings: WebSocket Secure (WSS) connections on port 443 must be available.</p> |
| </li> |
| <li> |
| <p>Verify proxy servers settings: The proxy transmits and intercepts WebSocket Secure (WSS) connections on port 443.</p> |
