One of our users (Let's call the user user A) has a very weird issue in Qlik Sense.

Whenever she tries to login to the hub or QMC the user is stuck on the bubble animation as seen below:

We have tried almost everything to solve this issue but we cannot seem to figure it out

What we have tried:

1. We haven given user A a professional license/rootadmin rights, user A still couldn't access the hub or qmc.

2. We have tried to login with a different account on user A's machine and this works. Once we try to login again with user A's credentials she is stuck again on the bubble animation. So we can exclude that this is a connection issue.

3. We have deleted the user A from the AD and added user A again, the same issue occurs.

4. User A has tried to login with her credentials on another machine and she got the same issue that bubble animation keeps loading.

5. We have checked the proxy log files on the server and couldn't find any errors, user A get's authenticated successfully.

6. We have cleared user A's browser cache, cookies and search history.

We are kind of desperate now so any help would be awesome 😄

Thank you in advance.
