We have unfortunately decided to remove Qlik Sense June 2019 from the download site temporarily. This is due to a significant degrade being identified where users experienced authentication issues when accessing the QMC or the Hub via a virtual proxy having a prefix. Currently, what we observed is that if you connect to a virtual proxy with a prefix, the request will be forwarded to the virtual proxy without the appropriate prefix.
This issue is currently being addressed and a new release will be made available as soon as possible.
We sincerely apologize for any inconvenience and we will keep you updated on developments.
