I have successfully installed Home Assistant OS 9.4 on my raspberry P4 three times, as well as OS 9.0 and OS 8.5, but none of them can display or load the add-on. I don’t know whether I’m doing something incorrectly, and after reading numerous articles, nothing has helped me with this issue.
This is the image link https://github.com/home-assistant/operating-system/releases/download/9.4/haos_rpi4-64-9.4.img.xz
1- Tested diffrent browses
2- Using fixed IP and (DNS 8.8.8.8, 1.1.1.1, Gateway IP)
3- I configured the Port forwarders (Port 80, 443, 8123) to the Home assistant server.
4- I installed OS 9.0 and I perform the Version Update to make sure the the server is connected to the internet.
5- I tried to add repository GitHub - hassio-addons/repository: Home Assistant Community Add-ons but it shows an error message “Can’t add GitHub - hassio-addons/repository: Home Assistant Community Add-ons, already in the store”
