Installtion on synology

hi everybody,

I installed homeassistant on my ds213air following this guide:
https://home-assistant.io/getting-started/installation-synology/
after a little bit troubleshooting the hass-daemon starts with no errors.
but I’m unable to access the website. "safari is unable to open the site 192.168.20.9:8123
firewall port is open on synology.
here the log file:
