I have had AdGuard Home for a few years now, running on my small Ubuntu server. All works fine, but my ISP turned CGNAT few weeks back. I have all my stuff running via Wireguard reverse tunnel to free Oracle VPS. Everything works, except AdGuard. I’ve tried to forward all necessary ports, but still my phone says Can’t connect. Is there any chance to get this running? The ads in apps are killing me.
Try asking isp to disable cgnat if you havent. Worked for me
