Kaspersky Blocking Internet in Cubase 15 (Heads-Up)

Just a small heads-up for anyone using both Kaspersky and Cubase 15 on Windows:

On my PC, Kaspersky was blocking all internet activity inside Cubase, even though my normal browser connection was fine.(this is a new case never happened before). When I closed Kaspersky, everything started working again.

It affected online features in plugins like Master Plan, Fuel, and Musio/SINE player (license checks, logins, etc.).

So if your plugins say “no internet connection” inside Cubase but everything else is online,👉 check your antivirus/firewall (Kaspersky in my case) it might be silently blocking Cubase.
