I am getting a failed to connect error when I try to use the iPhone app, it was working fine till now. when I use the internal IP it does not work. When I use the external IP on the app it works but can’t use it on my home wifi cause no NAT loopback. The error message is as followed "This certificate for server is invalid. You might be connecting to a server that is pretending to be “x.x.x.x” which could put your confidential information at risk.
I am running duckdns, and the cert expires in like 5 months. Does anyone know how to fix this?
