The error

Issue n8n-io/n8n#15246 (closed, 38 comments): ### Bug Description Hi there, I’m trying to use a Hugging Face model in n8n, but I’m unable to set up the credentials successfully. I obtained my Hugging Face token (which begins with hf_) and pasted it into the API Key field under Hugging Face credentials in n8n. However, when I save it, I receive the error message: “Couldn’t connect with these settings. More details.” Even after clicking the “Retry” button, the same error persists. I found that others have encountered the same issue when using n8n locally. However, I’m not sure if it’s caused by running n8n on YOUR_HOST. I’ve tried updating
