Reply To: port forwarding from web connection works, not app

I am using a a letsencrypt SSL certificate on my webserver (mydomain.com:80 redirects to mydomain.com:443) but not on my opensprinkler (so that shouldn’t be the problem)

I am using Android 10, not IOS.

You said “mydomain.com:1000 does not work”, but it does via a browser (not the app).
