Users have intermittent issue opening applications from the QlikView Access Point with IE Plugin client.
Users see "Failed to open document".
The observed error message indicates issues with failing call to the tunnel.dll
Environment:
The IE Plugin client communicates with the QlikView Server over port 4747. If tunneling isn't configured correctly in IIS, the error message will be returned. Tunneling is configured by default is using the QlikView Web Server.
The TicketData.pgo file has become corrupted, and a new version needs to be created. The TicketData.pgo file is transitory, so there is nothing in the file that will cause a loss of anything by recreating new versions. You may also notice in the QVServer Event logs that one server is creating a ticket, but the other server is attempting to consume it but the ticket cannot be found, and the reason is the 'shared' TicketData.pgo file is not updating correctly so the clustered servers have access to all tickets generated.
If the build version of the QlikView Server does not match the version of the IE Plugin client, this error may be returned. This is more prevalent when using a newer version of IE Plugin, such as 12.40.20000, and attempting to connect to an older build version of QlikView Server such as 12.10.XX/12.20.XX.
Verify that port 4747 is open. If port 4747 is blocked, QlikView will need to tunnel. If tunneling is not correctly configured, this will fail.
To verify if tunneling is correctly configure, navigate to the following URL: http://<servername>/scripts/qvstunnel.dll?test
See How To Configure Tunneling Using Microsoft Internet Information Server (IIS) if IIS is used.
Another option is to tick the Always Tunnel check box in QMX > System > Setup > QlikView Web Servers > QVWS@ > AccessPoint > Server Connections
Port 4747 being available is the preferred and recommended method. Tunneling should not be required.
Follow the steps below to confirm TicketData.pgo file is working properly:
There are two options depending upon if QlikView Desktop is also installed on the client computer.
