App doesn't connect to HA

I am trying to connect the app to HA but I only see the following page:

I guess the issue is related to my certificate which is issued by my personal CA and is not trusted from my Iphone. However, I always answer yes to the question, if I trust the certificate.

Does anyone have an idea what else I can do?


I am a bit further.
Using a manual (not the discovered) address based on the IP address it works.

This leads me to the conclusion that there is an issue with the certificate, which works perfectly in browsers.

I guess this is a bug in den app and therefor I’ll file an issue in Github for this.

If you are using duckdns, there is an ongoing issue.

No - I use my personal local DNS server.
