Qlik Data Transfer not reading HANA 64 bit connection

[venus_19]

My QDT had a SAP HANA 64 bit connection made and it was working fine till 7th Feb. Suddenly, it stopped reading the connection. I tried reinstalling QDT, making the connection again but nothing is working.

Please confirm that your HANA driver and SSL certificate are valid and functioning properly.

If everything is fine on that side, kindly verify that the username and password used for the HANA connection have not expired. If the password has expired, please update the connection with the new password.

This sudden failure (starting around Feb 7) is almost certainly due to Qlik Data Transfer (QDT) reaching its End-of-Life in Q1 2026 (official EOL by March 31, 2026, with support extended to April 30 in some notices). QDT is no longer actively maintained, and many users report ODBC connections—like your SAP HANA 64-bit DSN—stopping working reliably in early 2026, even after reinstalls, recreating the connection, or DSN tests succeeding in Windows ODBC admin. Temporary fixes (service restart, clearing C:\ProgramData\Qlik\DataTransfer\ folders) rarely last.

Recommended permanent fix: Migrate to Qlik Cloud with Qlik Data Gateway – Direct Access (the official replacement). Use the native SAP HANA (Database) connector (no ODBC needed, more stable) or ODBC via the gateway. Check the deprecation notice here: https://community.qlik.com/t5/Support-Updates/Qlik-DataTransfer-Deprecation-Notice-for-Q1-2026/ba-p/... and gateway setup: https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/Gateways/data-gateway-di.... This eliminates QDT issues entirely—many have switched successfully for HANA sources
