So after alot of trial and error i got the AI Framework & Core to connect just fine.
However Rimind , Seems to have some kind of formatting error i suspect.
As my LMStudio Log shows an error 200 when it tries to connect, so it gets the message but doesn't know what to do with it.
I've tried tweaking things with everything i can think of to no avail.

Here is the Github Logs from Harmony.. right around lines 5854 is when i get it to work

My Guess, is that you have something going on with the Models and Get Models method within Rimind, instead of using the AI Framework to connect through the already established connections and it's not working.

If possible maybe just connect that way and when a user selects a LLM or KoboldAI setting, direct them to change settings within the AI Framework since you already require it anyway.
