Proxy Error 500 Janitor AI | How to Fix it

Proxy Error 500 on Janitor AI means the connection between the site and the AI model has failed. It is not a problem with your internet, but rather a failure of the “brain” (the LLM backend) to generate a response.

This is likely happening because the specific model you are using is overloaded or your API key has expired.

Here is how to fix it, depending on which AI model you are using:

How to Fix it

1. If you are using the “JanitorLLM” (Free Model)

If you are using the site’s default free AI, Error 500 usually means “Server Overload” or “Context Overflow.”

• The “Context” Fix: The most common cause is that your chat history is too long for the AI to read in one go.

  • Go to Generation Settings (top right menu).

  • Lower the Context Size from 9000+ to 4096 (or lower).

  • Why? If the chat is too huge, the server times out trying to process it, triggering Error 500.

• The “Waiting” Game: If the error says “Exhausted all available targets,” it means the free GPU cluster is full. You must wait 5 to 10 minutes before sending another message.

2. If you are using an OpenAI / Kobold / Proxy Key

If you are bringing your own key (OpenAI, Claude, or a Reverse Proxy), Error 500 means your Key is invalid or the Proxy URL is wrong.

• Check your Balance: If you are using OpenAI, check if you have run out of credits. (OpenAI does not allow free tier API usage anymore; you must have a paid balance).

• Verify the Proxy URL: If you are using a custom endpoint (like a KoboldAI link), ensure the computer hosting it is actually online. If that computer goes to sleep, you will get Error 500 immediately.

• “Reverse Proxy” Users: If you are using a “free OpenAI proxy” found on Discord/Reddit, those keys often get banned within hours. You likely need a new key.

3. The “Corrupted Chat” Glitch

Sometimes, a specific message in the chat history breaks the AI’s logic.

• Test: Start a New Chat with the same character.

  • If the New Chat works: Your old chat is “corrupted.” You may need to delete the last few messages in the old chat to “un-stick” it.

  • If the New Chat fails: The entire site/model is down.

4. Browser & Cache (The UI Fix)

If the error pops up immediately when you load the page (before you even chat):

• Clear Cache: Go to browser settings and clear cookies/cache specifically for janitorai.com.

• Switch Browsers: This error is notoriously common on Safari (iPhone). Try using Chrome or Firefox instead.
