How can you enable remote access on HomeAssistant installed on a Synology DS218+ through Docker?

I’m doing all of the above, but with duckdns. I can access the ha locally but via the external address I’m getting SSL errors, the ha log is also showing http errors. Does my http config require a change? I have the base URL only in the config. I have an open /ticket with a full breakdown of my problems.
