Hello Selfhosted!
So I have an interesting issue. I have a docker host, and that host i have a Caddy container. I have that setup to handle reverse proxying. I have it setup to be local only. I have a pihole and a wireguard server. And can connect to my network successfully.
The part that confuses me is that while on network everything works great. While on VPN I can connect to services by IP:Port. If I use mobile data with VPN, I can’t use the site addresses. x.domain.xxx (for privacy sake I’m leaving my domain out of the post.) But when I connect to WiFi, any WiFi, and connect to VPN I can go to the address I have setup for reverse proxying.
I am unsure how to troubleshoot this. Any pointers would be appreciated.
In that case, are you sure the VPN is actually on, when on cellular?
Absolutely, I can connect to the services via IP:Port
Beats me then. Network wise an external Wifi should follow the same rules as an external cellular connection.
I don’t have a lot of networking skill here, but could it be your WiFi connections (anywhere) are IPv4 and on mobile it forces IPv6, thus why you can connect via IP:port? Typically your wireguard host machine has IP forwarding/masquarading setup so you can reach your home LAN. Could this be an issue through the router / proxy?
