Issue Details

My network provider may have blocked port 123, which prevents me from starting the Adgurd service normally after updating to v7.15, but it works fine when I roll back to v7.14;

I found out through network diagnosis that Adguard tries to connect to 20.189.79.72:123 via UDP when starting (possibly resolved from api.adguard.org), and if the connection fails, it cannot start the Adgurd service successfully;

After testing, I can solve this issue by using port forwarding, or changing the network environment (network proxy).

Expected Behavior

Change or cancel this behavior of Adguard at startup; to solve the issue of being unable to start the service normally when Adguard fails to connect to 20.189.79.72:123 via UDP.
