Kicked out of app all the time!

Hi

Here is the problem. We have few iPads running the HA companion app. At first we were using a unique HA account for all iPads. They were being kicked out all the time (disconnected from HA stating that credentials were refused by HA).
We have created one user account per ipad and we still have exact same problem. I get a popup in HA companion app stating credentials refused and I have to login again :frowning:
The app is basically unusable on iPads due to that. Any ideas what’s the problem ? Nothing fancy in network (Unifi based). Tested with iPads in DHCP or fixed IP address in DHCP, no change. Ipads are in current iOs release.
Logs of HA when an iPad is kicked out:

Not sure what to test else to find out what is the problem :frowning:
