Using a Qlik signed license in an offline environment
Can a signed license key be used in an environment disconnected from the Internet?
Qlik Sense and QlikView are available with two license models:
LEF license (old model)
A signed license key requires the Qlik Licensing Service to have connectivity to the Licensing Server. If the system remains offline for too long, end user access will be affected. Qlik Sense April 2020 and later supports Delayed Sync, which allows for the product to operate for 90 days before internet connectivity is required. See Activate Qlik Products without Internet access - April 2020 and onwards.
Qlik Sense is installed on a host without internet connectivity. It was temporarily connected to allow for the license to be enabled and was disconnected afterwards.
Two days later users are unable to consume consumption licenses. 5 days later, end-users see You have no access passerrors when opening the Qlik Sense Hub.
A signed license key requires connectivity over port 443 to license.qlikcloud.com.
A LEF license can be used in a single environment without an active connection to license.qlikcloud.com, but functionality of LEF license is restricted. LEF licensed systems cannot take advantage of Analyzer Capacity, Multi-Cloud deployments, or Unified Licenses.
