We have recently upgraded to May 2023 Patch 4 version. After upgrade some of the tasks are failing with the below mentioned error but the connections refreshes are successful if we run locally.
@abi_qliksupport The error is related to TLS, and this is mostly related to the error you see during the task load. The correct TLS version and ciphers need to be enabled on the QlikSense servers.
Please follow the steps from the below articles and either run the script manually or use the powershell script to enable necessary TLS and ciphers for QlikSense. This should be performed on both Central and RIM nodes.
