This article is for users who encounter DNS leaks in Google Chrome or Mozilla Firefox while connected to ExpressVPN.

DNS leaks occur when a DNS query is made outside the VPN tunnel. Google Chrome and Mozilla Firefox’s DNS over HTTPS feature bypasses ExpressVPN’s DNS and runs DNS queries outside the ExpressVPN tunnel.

In certain regions, like the U.S., this setting is automatically enabled.
