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.dllEnvironment:
QlikView any version
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. Port 4747 being available is the preferred and recommended method. Tunneling should not be required.
TicketData.pgo file corruption
is a possible root cause of this issue.
Follow the steps below to confirm TicketData.pgo
file is working properly:
- Go to C:\ProgramData\QlikTech\QlikViewServer and confirm the TicketData.pgo file timestamp is updating with each user login.
- Go to the location of your QlikView Server Root Folder path as specified in the Management Console under System\Setup\QlikView Servers\QVS resource\Folders tab, by default this will be C:\ProgramData\QlikTech\Documents to verify the copy of TicketData.pgo is also updating with each user login.
- If either of the above timestamped TicketData.pgo files is not updating, stop the QVS services on each server running them in the clustered configuration, and then remove all copies of the TicketData.pgo file and then restart the QVS services.
- Verify all copies of TicketData.pgo are not updating as expected. Generally the size of the TicketData.pgo will be 1KB, so another thing to check is the file size as well, and if it is larger than 1KB, this may also indicate a problem with the file, and Step 3 should be done as well.
