I've got this problem and unable to post on the community as discussion please guide me ltu especially your reply shall be appreciated really
Thanks In Advance everyone.
I've installed Qlik Sense Enterprise April 2018 on a machine with windows server 2012r2, everything is working fine except one thing i.e. when I open an APP on hub and let it be opened for 3-4 minutes without performing any activity following error is displayed saying "An error occurred: Not connected"
Have someone also faced this situation and solved please let me know.
NOTE: The Solutions I've tried are,
License renewal: Changed the license as found in researches.
Token allocation: Allocated login access passes while creating the license security rule i.e. user.Isanonymous()
Log: Also gone through Logs in Crogramdata/qlik/sense/log but there was nothing noticeable.
Host WhiteList: the other solution was to write the machine name in the Virtual proxy>Host White List
The proxy log gives the following error.

May be there were some server objects associated with 2 logon ID’s, check that they are working with the company or not. Delete those server objects and copied the .meta and .shared files back to required environment.
Before going deeper I would suggest to restart the whole server to be sure that there isn't any temporary issue. may be check for other service up-gradations happened recently, shutdown & restart all services.
