OMG I got it working. I enabled the CORS (Cross-Origin Resource Sharing) setting on LLMStudio and now it works. So it was something on my end. LLMStudio probably screwed up when it updated.
ah, interesting. glad that you were able to get it working. that setting is supposed to be on by default but I guess something messed it up. I will add a short how to setup button similar to the one for image-gen which will hopefully help others in the future.
