Cannot Lease License in QlikView 12.9 Security Settings Denies Access

spring101 — Mon, 26 Jan 2026 18:19:17 GMT

We are in the process of upgrading our QlikView environment to 12.9. We have a test server where we installed QlikView desktop 12.9 and are attempting to lease a license from our production server which is currently on 12.7. Port 4747 is open on both machines. However, we are seeing the error message 'Security settings denies access'. Has anyone else encountered this? If so, what setting needs tweaking?

Thanks in advance!

Hello @spring101,

In QlikView v12.80, the security algorithm was changed, so there's a mismatch between your 12.70 QVS and your 12.90 QV Desktop.

Have a look at the following articles which should assist in getting this issue resolved:

Open in Server fails using QlikView Desktop May 2023 or later against earlier version of QlikView Server
How to set a different Session Algorithm for QVP communication in QlikView 12.80 and later
