I will go through the process. Been in the software biz for a very long time. I get how to trouble shoot things – I didn’t post until I tried many different options. What was strange is that the Android app obviously had the correct internal and external urls for many months. Seemed odd that an update on the server removed it. Admittedly, I’m very light in my knowledge of Android.
If it matters, I run my HA in a Docker container using docker-compose to manage it along with 14 or so other containers.
