We can't handle the communication between the Qlik Sense SaaS and the Data Transfer with a proxy.
Most Japanese companies use proxies.
So we would like to configure the communication between the Qlik Sense SaaS and the Data Transfer to be handled by a proxy, like the communication between the Qlik License Service and the License Back-end.
it's really a problem that Qlik (which offers products for enterprises) does not systematically provide support for proxies, example : CLI, Data Transfer
By the end of this quarter Qlik will release Data Gateway - Direct Access, targeting enterprise deployments that are challenged getting their on prem and private data to Qlik cloud.
