Hello folks,
I am attempting to connect to a QS Enterprise instance with the QS Enterprise Scalability tools. Could anyone please help me understand potential root causes and resolutions for the following error:
Version: v0.17.11 Failed to connect using 2 connection test functions. Error #1: failed to connect to engine over web socket: Failed connecting to sense server: Failed connecting to sense server: Error connecting to Sense: unexpected websocket scheme: "https" Error #2: HTTP request fail: Get "https://t***d/login": lookup t***d on xxx.xxx.xxx.xx1:53: server misbehaving
Thanks,
Jeff Robbins
Hi DataWrangler, maybe this will help:
The error message indicates a WebSocket connectivity issue between the client and the Qlik Sense server. This could be caused by several factors:
1. WebSocket support may not be enabled or configured correctly on the client side, third-party proxies, reverse proxies, or firewalls. Verify WebSocket connectivity by navigating to https://websocketstest.com/ from the affected client.
2. The address being used to access the Qlik Sense Hub may not be added to the Host White List in the proxy. Add the address to the WebSocket origin white list in the Qlik Sense Management Console under Virtual Proxies.
3. Check if the Qlik Sense Engine service is running and accessible. Ensure the necessary ports are open and not blocked by firewalls.
4. Verify the SSL/TLS certificate used for the Qlik Sense server is valid and trusted by the client. Replace any self-signed certificates with trusted certificates from a Certificate Authority.
