Frontend listen on https on docker

i setup hass as a docker container on my Synology NAS. Hass is running fine. I also setup the access to my nas via a lets encrypt certificate with works also fine.

No I like to connect to hass via the Synology dns name on the port 8123 via https. But hass did not answer or redirect.

Is this doing possible or have I use a different way?

Thx for your help.

Synology dns name likely point to port 80(http://synology) or port 443(https://synology)

You may need to setup something like nginx and use reverse proxy to forward request to HA
