OpenRouter AI Error 401 – {“error”:{“message”:”No auth credentials found”,”code”:401}}

You’re using the wrong or expired API key.

• Fix:
  • Check your API key, or you can regenerate your new API key.
  • Double-check that the model name and proxy URL are correct.
  • Go to OpenRouter > Settings > Privacy > Turn ON “Model Training”.
  • Avoid mobile shortcuts—use a real browser tab.

Proxy Error 402 – {“error”:{“message”:”Insufficient credits”,”code”:402}}

This means you’ve hit OpenRouter AI free tier limits, even though you’re not paying. Free users have a daily credit limit, and it is reset every 24 hours.

• Fix:
  • Wait for the reset or create a new OpenRouter account (sometimes it works, and sometimes it won’t).
  • Refresh the page and try again later.
  • Use a different free model if available (like DeepSeek-V3).
  • Try during off-peak hours.

Creating new accounts often doesn’t work because:

• OpenRouter detects duplicate accounts.
• They may block new free accounts during high traffic.
• The free credit pool might be temporarily exhausted.

As a last option, you can use a reliable VPN for new accounts. Check below for a good VPN that works well in this situation. It performs best when your internet connection isn’t slow. Also, try using a different browser — for example, if you’re using Chrome, switch to Firefox or another browser.

OpenRouter Proxy Error 404 – {“error”:{“message”:”No endpoints found matching your data policy”,”code”:404}}

• You didn’t turn on model training.
• Fix:
  • OpenRouter > Settings > Privacy > Enable “Model Training”

A network error occurred, you may be rate limited or have connection issues: Failed to fetch (unk)

You spammed too fast, or your internet dropped.

Rate limited = too many requests in a short time.

• Fix:
  • Turn off your Wi-Fi connection and use the mobile connection.
  • Reload the page with a mobile connection.
  • Turn it back on and reroll.
  • Double-check the Model name (no typos or spaces)
  • Proxy URL must be exactly: https://openrouter.ai/api/v1/chat/completions

OpenRouter Proxy Error – No response from bot (pgshag2)

This error occurs due to Targon because Targon is causing issues.

• Fix:
  • OpenRouter > Settings > Ignored Providers > Add “Targon”
  • Wait for a few minutes and try.
  • You can try DeepSeek V3 or a less crowded model.

Proxy Error 500: Internal Server Error

Likely, it’s happened due to a broken API key or Proxy URL.

• Fix:
  • Check your API key and URL settings.
  • Check that the OpenRouter is working. You can check on – status.openrouter.ai
  • Wait it out or try another model if needed.

Unknown response: [object Object] (unk)

Most likely, it’s OpenRouter just overloaded with users. Maybe you can try Deepseek through the Chutes AI. It’s more stable. It’s happened due to an often rate-limit or config issue.

• Fix:
  • Check that your Janitor AI settings are correct.
  • Second, you can wait or make a new account.

OpenRouter/Chutes Prompt: Token Limit Exceeded

You’ve hit your daily 50-message cap because this is all that’s available on the free plan.

• Fix:
  • Wait for the reset of your credits, or you can use a new account.

OpenRouter Internal Server Error (unk)

Due to the Overloaded free-tier model or an unknown bug.

• Fix:
  • Try to refresh the API key.
  • Switch to another DeepSeek model like V3.
  • Wait for 4-5 minutes and try again.

Provider Returned Error (unk)

It’s happened due to Server down, rate-limited, or a bad/expired API key.

• Fix:
  • Block Targon in the (OpenRouter AI Settings > Ignored Providers).
  • Refresh Janitor.ai and try again later.

Proxy Error 405 (unk)

Likely, it occurs due to an invalid request or an issue in URL configuration.

• Fix:
  • Confirm this Proxy URL: https://openrouter.ai/api/v1/chat/completions
  • Refresh API key: openrouter.ai/keys
  • Block the Targon provider in the OpenRouter settings.
  • Wait 15–20 minutes and retry.
  • Switch to the DeepSeek-V3 model if needed.

Proxy Error 408: Timeout (unk)

The OpenRouter AI server didn’t respond in time. It’s happened due to too many requests, server overload, and slow internet connection.

• Fix:
  • Please wait 2 minutes and resend your message.
  • Check your internet – switch to a high-speed internet connection.
  • Refresh your API key (old keys sometimes time out).
  • Block the Targon provider in the OpenRouter settings.
  • As a last resort, try late at night or early morning when servers are less busy.

The proxy URL should still be exactly: https://openrouter.ai/api/v1/chat/completions

OpenRouter AI Network Error

It’s Common during overload, or your internet connection is unstable. Free models have limited capacity that gets overwhelmed during peak times. You’re essentially waiting in a digital queue.

• Fix:
  • Verify that your internet is working correctly.
  • Confirm that the model and Proxy URL are right.
  • Wait 5–10 minutes and retry again, or try in early mornings or late nights (UTC time)
  • Switch to the DeepSeek-V3 model if needed.
  • If it fails, reload twice max – more triggers rate limits

Pro tip: Bookmark OpenRouter Status – the color-coded graph shows when free models are most available (green = good times to retry).

This error doesn’t mean you did anything wrong – it’s the system managing limited free resources. Persistence (with smart timing) usually gets through.

OpenRouter Proxy Error 503: Maintenance (unk)

This basically means the Chutes.ai or DeepSeek servers are currently down for maintenance or experiencing technical difficulties.

• Fix:
  • When you see this, the best thing to do is just wait it out for a bit and try again later, as the team is probably working on updates or fixing something behind the scenes.
  • If it stays down for an unusually long time, you could temporarily switch to a different model, but most of the time, these maintenance breaks don’t last too long before everything’s back up and running normally again.
