@parsidian We'll check your logs, please some time

@parsidian Judging by the logs, there are no entries related to RAM. Please describe in more detail how AdGuard stops working.

1. Does it shut down completely or restart?
2. How do you know that AdGuard is turned off?
3. Is the VPN profile icon in the system tray at the top of the screen active at that moment?
4. What is displayed on the Home tab in AdGuard?
