My current setup involves a Raspberry Pi running wireguard in my LAN with a daily changing WAN IP. Thus, I connect to my RPi via a Dynamic DNS address, which is automatically updated after each forced disconnect of my ISP. I use the Android app with the "always on" option, but wireguard fails to properly reconnect to my RPi after the DDNS changes. Is there already a solution in place to maintain a continues connection in this kind of scenario? If not, would you be willing to accept patches to resolve this? If so, what would be an acceptable adjustment? Sincerely, Oli
