Unifi has published an Advisory To Change the password and enable 2F authentication after an incident. Check and ensure your security settings are correct. Sometimes the Unifi devices get disconnected from the controller and then we need to re-connect them. Sometimes they show us an error Inform Error, refer to the attached article to deal with Inform error issue. Do not forget to refer to the article if you are looking to Upgrade the Firmware of the Unifi controller. The attached article contains a step-wise method to upgrade the firmware of the controller.
