The Qlik Sense Desktop Authentication Link and iOS Mobile App Authentication link, can be distributed from any virtual proxy, but can only be made available through the hub from the central proxy. See the official Qlik Online
help for details.
You can generate an authentication link for any node and distribute the link manually. However, if you are generating a link that will be retrieved from the Qlik Sense hub, you must select the default virtual proxy on the central node.
This is currently working as expected. Environment:
Qlik Sense any version
If the desktop link needs to be submitted from a virtual proxy, eMail or an EMM (Enterprise Mobile Management) need to be used to do so.
Qlik has previously received feedback on this feature and recorded the request for future review. For up to date information, please contact support, referencing this article.
