An error occurred. Connection lost. Make sure that Qlik Sense is running properly.

Dear all,

I have a QAP server and it is already "out" in internet, I can access via https://server.at/qmc without problem. But when i try to access my mashup i get the following error:

An error occurred.

Connection lost. Make sure that Qlik Sense is running properly.If your session has timed out due to inactivity, refresh to continue working.

I am sure i am missing something very small! But i have tried everything!  (in the white list i have every possible name and every possible IP address, i have opened the ports 443,4244,80,4248, i've tried with http and https)

Any ideas?

thanks,

regards,

Emma

Do you find any errors in proxy logs. Try disabling firewall to make sure its not the firewall issue. Below are the ports we had to allow in firewall for us to get everything working, see if this makes any difference for you.

80, 443, 3003, 4144, 4239, 4241, 4242, 4243, 4244, 4248, 4747, 4748, 4239, 4432, 4444, 4545, 4555, 4747, 4899, 4900, 4949, 5050, 5051, 5151, 9028, 9031
