Qlik Sense mobile app login error

[oscarvictory]

Hi all, hope you can help me.

I've just installed Qlik Sense on Server, allocate user and create the Client authentication link under http.

Question is that from android Mobile APP i'm stuck with error:  "The attempt to log on to the server has failed".

Is there any QMC configuration missing from my side? all ports required are open.

Many TKS in advance.
