AdGuard for Linux is not filtering traffic or has connection issues. What should I do?

If AdGuard for Linux is active, but does not work in your browser, the browser may be ignoring system proxy settings or there may be conflicts with VPNs/extensions. Make sure filtering is enabled, filters are up to date, and there are no conflicts with VPNs or DNS settings.

Check if the local proxy is active and correctly configured. Also ensure there are no conflicts with other networking tools, firewalls, or iptables rules. In some cases, IPv6 or DNS settings may require additional adjustments. Some browsers may ignore system settings or use protocols like QUIC or DoH.
