No access to Qlik -> license lost

[w_a]

Hello, 

We had some strange behaviour with Qlik Sense Enterprice. 

Users could not access hub (there was errror that said they have no acess pass).  In qmc there was nothing wrong. We restarted services. Then  we acess qmc and there opened tab with lisence managment which asked us to type the license key.

After licence key is typed everything was ok again. 

Now my question is. What are possible causes of this errors? Why license dissapeared?
