Common Issues with LM Studio

See detailed troubleshooting guides for the most common LM Studio errors:

API Error (500 / 502 / 503)

When LM Studio returns an API error (HTTP 500, 502, or 503), it typically means the servers are experiencing issues, undergoing maintenance, or handling an unexpected surge in traffic. This is usually a server-side problem, not something wrong with your code.

Rate Limit Exceeded (429)

A 429 'Rate Limit Exceeded' error from LM Studio means you've sent too many requests in a given time period. This is a protective measure to ensure fair usage across all users. It can be triggered by your individual usage or by LM Studio-wide capacity constraints.

Timeout or Slow Response

When LM Studio is timing out or responding very slowly, requests take much longer than usual or fail entirely. This can affect both API calls and the web interface. Slow responses often indicate server overload, network issues, or problems with specific models.

Authentication Failed / Invalid API Key

An authentication error from LM Studio means your API key, token, or login credentials were rejected. This can happen when keys expire, are misconfigured, or when LM Studio's authentication service itself is having problems.

Model Unavailable / Overloaded

When LM Studio reports a model as unavailable or overloaded, the specific AI model you're trying to use cannot process requests right now. This is often temporary and happens during peak usage times, model updates, or capacity issues.
