So my guess was 100% correct. Kaspersky was checking all the HTTPS traffic and converting http3 to http2. I blocked these two URLs from my network. ksn-url-geo.kaspersky-labs.com ksn-verdict-geo.kaspersky-labs.com And then now my browser can use the http3. So the issue is with Kaspersky.

I am using latest version of Kaspersky Internet Security Windows 11 PRO 22H2 My browser is Brave Browser with the latest build. I have enabled http/3 through Adguard Home. So under the same wifi network, on Android Mobile/Android Tablet http/3 is working. But on windows 11 computer, where kaspersky is installed, it's blocking the http/3 connection. (I have enabled quic support on the browser aswell) I have checked it using http3.is website. Please allow users to use http/3, it's faster.

Thank You for this. So I have checked with this, I can find out the IP which is trying to connect, but still couldn’t find which software was trying to connect with this domain - fun-cc.azurewebsites.net netstat -abn (Also show similar info like tcpview) but only the IPS.

Hello, I was checking my Adguard Home Traffic, and then find out a weird domain called “fun-cc,azurewebsites,net” was trying to connect to the internet from my computer IP. I have blocked the domain, but I still couldn't figure out which software/applications were trying to connect to this domain. I believe it's malware. So with Kaspersky is there any way to check (probably with network monitor or application manager), which application is trying to connect with this specific domain? I am using Kaspersky Version: 21.3.10.391 (g) Windows 11 (Up to Date)
