I copied in a flow example and its seems like the generic server settings from one of the nodes has caused some error.
Home assistant connection failed with error: Connection to home assistant could not be established with config: https://yourdomain.duckdns.org:8123 <password redacted>"
Deleted the imported nodes and only have the one server that I can see in my nodes.
I’m still connected to my server and everything else is working fine.
