@Etienne , @Wesly.Zhang Thank you. Setting an exclusion for the browser worked! Got the same problem. but with the sollution of Wesly it worked for some part. go to “Settings” → “Protection” → “Application Control” → “Manage applications” and find your browser u are using. right click on your bowser and choose “Details and Rules” in the pop up window go to “Exclusions” and check “Do not scan all traffic” type the ip of your unifi controler in “Only for specified IP addresses”: click save and that solved my problem :) hope this helped u out!

Running Kaspersky Internet Security 21.1.15.500(c) on Windows 10. I can only access the web interface on my Ubiquiti UDM at 192.168.1.1 by turning off Settings|Protection|Web Anti-Virus. It can be turned back on after the login page renders. I tried intermediate steps of adding 192.168.1.1 to the various exclusion lists at Settings|Protection|Web Anti-Virus, and deselecting various scans/checks in that section of Kaspersky. The only way that I could access the UDM was by completely disabling Web Anti-Virus. The UDM is a UDM Base running 1.8.4-2.
