Overview
There are certain network requirements that are necessary in order to use sensemetrics. Internet Browser versions will need to be up to date as well as WebSockets enabled.
Browser Requirements
- Google Chrome 16+
- Firefox 11+
- Safari 6+
- Microsoft Edge 38+
Although Internet Explorer is not officially supported, we do make an effort to keep the site functional in Internet Explorer 11. You may experience some issues due to the lack of broad support of official web standards.
WebSockets
WebSocket is an Internet communication protocol providing bi-directional data transfer between a web browser and a web server over a single TCP connection. WebSockets facilitate real-time data transfer to and from a server and can greatly enhance the features and usability of web applications.
How to Enable WebSockets
While most network configurations support the use of WebSockets, some networks which feature firewalls or proxy servers can block WebSockets from functioning. If your WebSockets are not enabled, try the following:
- Older web browsers do not support WebSockets, so it is important to keep your browser up to date.
- If your network uses a firewall, ensure that it is not blocking WebSocket traffic on TCP port 4000, 4001, 4200, 4201. You may need to contact your organization's IT personnel to confirm this.
- If your network uses a proxy server, ensure that it is not blocking WebSocket traffic on TCP port 4000, 4001, 4200 and 4201. Since WebSockets are a relatively new protocol, many proxy servers do not support it. Your proxy server may need to be upgraded to enable WebSocket support.
