I installed OpenVPN VPN solutions on Ubuntu for my businesses to secure all data communications. I also set up Pin-hole ad blocker on Ubuntu server along with OpenVPN. How do I force Pi-hole to use Cloudflare DNS over HTTPS (DoH) to increase my privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks?
I installed an OpenVPN server with Pi-hole software to block block ads, reduced my 4G/3G/LTE traffic on the same Debian or Ubuntu Linux server. How do I upgrade my Pi-hole to the latest version using command line?
