Occasionally you might have trouble accessing UXPressia and see an error message saying that you are offline.

This might result from your network connection/environment issues or limitations.

WebSockets

To learn what happened, start with checking your WebSocket connections. For that, open the link http://websocketstest.com/.

You will see a similar screen if your connection supports Websockets:

websocket uxpressia

If the screen is different, most likely your connection doesn’t support Websockets. In this case, try the following:

  • Connecting to another network;

  • Turning on/off VPN.

If you use a corporate connection, reach out to your network administrators and request enabling Websocket connections on 80 and 443 (SSL) ports.

Firewall

If you use a Firewall, be sure to allowlist UXPressia’s domain uxpressia.com.

Proxy

If you use a proxy, you need to add a by-pass for our platform.

proxy uxpressia

To do that, ensure the following:

  • The server supports WebSocket (HTTP/2) connections.

  • The proxy HTTP version is 2.

  • Source port is 80. We use this port 80 for users who access UXPressia through HTTP to direct them to HTTPS.

  • The destination port is 443 (SSL). 443 is used for HTTPS.

  • The Protocol is HTTPS.

  • TLS is set as 1.2.

  • The timeout value on your proxy server is 120-180 seconds.

  • The proxy server does not truncate request and response headers. For that, the client should proxy the Upgrade and Connection headers.
