I have been working with an HA running in docker (Synology NAS) for a couple of months. I configured the HTPPS and generated the certiicates. After beeing 2 months wotking via HTTPS without any problem it suddenly stopped working.
I tried to generate certificate again but it is still not working, it says “Unable to connect to Home Assistant.”
It is really strange because I did not change anything in my home/lan/domain configuration and the docker container was updated 4 days ago but it was working with that version without any problem until today.
If i change my configuration.yaml to work via HTTP (commenting certificates lines), it works without any problem via local IP.
Does anyone any idea about what can I do/try?
