HTTPS works with web browser but iOS app gives NSURLError -1004

Configuration Frontend

I have a FQDN which points to my HAAS install which is using SSL. Everything works as expected outside of my network (both web and iOS) and everything works fine internally with a web browser, but on the iOS app, although the app can properly discover my HA instance, trying to connect to it yields a NSURLError -1004. I’m really not sure what’s going on here because a NSLOOKUP properly resolves the address.

I’ve read a ton of posts on this and tried many suggested solutions, but none seem to address this issue. Any help would be greatly appreciated.

Have you ever been able to solve this issue? I experience the same.

Outside connection is fine
Internal only Webbrowser is working. The IOS app can’t connect, even after a reinstall.

I did get it solved, but unfortunately I really can’t remember what I did now. That said, do you have a Ubiquiti network setup? I believe I resolved mine when I moved some things around and had a little more control over the reverse DNS.
