Problem with installation

hi can anyone help me i installed home assistant on my rasbarry pi 4 via rasbarry pi os but when searching on the net i can’t find it only find it from the app

Do you mean you can access HA, but only with the app, not with a browser?

If http://homeassistant.local:8123/ doesn’t work, you could try giving the explicit network address - eg http://192.168.1.123:8123/

Also, https won’t work - the problem may be your browser settings.
