Call a self hosted web api from an Android app through a DDNS

Question

My client has an account with NoIp. Our goal is to allow an android app call our self hosted Web Api service through the NoIp dynamic ip. I've looked all over for some guidance on this topic, but I haven't found anything remotely related. Everything works in the local environment, android wired to local machine, Visual Studio 2019, using localhost. We've opened ports on the house's router. When I change the outbound ip to that in NoIp, still can't connect. Can anyone point me in the right direction?

Answer 1

I moved to a new house and was unaware that there was a wired internet modem that was connected to a wifi router. Ports had been opened on the router, but not the modem.
