Local access/automation not saving after DuckDNS

Hi all, I’m a newbie migrating from home bridge. I enabled DuckDNS so that I could access my home assistant from outside the local network and since then have run into some issues.

My automations disappeared and now I can not save them using the UI editor. Do I need to add a flag to my configuration.yaml to get them enabled again?

Also, if I access MY DOMAIN.DuckDNS.org it loads instantly on an outside network(Cellular) but if I’m on my home Wi-Fi it is super slow to load anything.

TIA
