I now tried several times to setup pentagi (also with the installer) but always fail at this point. Does anyone have an idea?

@XenGi : I ran in to the exact same error and from one of the other issues i found that you got to have a key from one of openai or bedrock or i want to say claude, if not you are going to run in to the above error(atleast that's what I ran in to). i added openai at the top and now everything is working. I could be totally wrong here, but when i tried with my own custom endpoint, i ran in to the same error as you. Good luck.

Ref: #203

hey @XenGi

@ganeshpalanisamynttr-cloud totally right, it's an issue with LLM backend integration, 404 returns from provider side.
which LLM backend or cloud provider do you use?
