Problem: Error message says “Invalid API key” or authentication fails. Solutions:- Verify you copied the entire key without spaces
- Check if key has expired or been revoked
- Regenerate a new key from provider dashboard
- Ensure you’re using the correct key format for the provider
Connection fails
Problem: Cannot connect to AI model or requests timeout. Solutions:- Check your internet connection
- Verify Base URL format (for OpenAI-compatible APIs)
- Try without VPN or proxy
- Check if the provider service is operational
- Verify firewall isn’t blocking the connection
Rate limit exceeded
Problem: Error message says “Rate limit exceeded” or “Too many requests”. Solutions:- Wait a few minutes before trying again
- Upgrade your API plan for higher limits
- Switch to a different model temporarily
- Check your provider dashboard for usage limits
Model not available
Problem: Selected model doesn’t work or returns errors. Solutions:- Verify the model ID is correct
- Check if you have access to this model
- Ensure your API tier includes this model
- Try a different model from the same provider
Missing required fields
Problem: Cannot save configuration, fields are incomplete. Solutions:- For standard providers: Only API key is required
