Determining the cause of a failed Qlik Sense hub connection

When you receive information that an error has occurred when attempting to connect to the Qlik Sense Hub, you should refer to the Qlik Sense Proxy Audit logs, normally found in the C:\ProgramData\Qlik\Sense\Logs\Proxy\Trace folder.

This log file generally contains much more detailed information on what caused the connection to fail. For example:

Http request origin is not allowed: https://10.76.196.135. White list for allowed origins are configurable for the proxy service: Current white list . Allowed host names:QlikServer1.domain.local , QlikServer1 , localhost , 127.0.0.1 , ::1 , 172.16.16.100 0 52537f68-f687-4f36-b2af-c360cea01c85    ::ffff:10.88.1.135 e003a863-ba21-42b9-8a01-f055983428b7  {} 7630d378e3b000b3dea6bbb2e9cc92ac13d6fd76

In this instance the connection failed because the hostname used to connect to the server was not included in the WebSocket Origin Whitelist/Host White List

Add the hostname to the Websocket Origin Whitelist/Host White List. Refer to Error Message "An error occurred Connection lost" When Connecting To Qlik Sense Hub for instruction on how to do so.

If you are unable to determine the cause of the connection please ensure you include the proxy log files in your case when you contact support.
