Hey, thanks for the report.

Please try:

  1. Settings > Network > Run Diagnostics, then send the results
  2. App Settings Cmd/Ctrl+, > search for HTTP/2 > enable “Disable HTTP/2”, then restart Cursor
  3. If you’re using a VPN or a proxy like Zscaler, temporarily disable it and test on a mobile hotspot
  4. Update Cursor to the latest version
  5. Create a new chat

If that doesn’t help, please send:

  • Your OS and Cursor version (Help > About)
  • A fresh Request ID (chat menu > Copy Request ID)
  • Logs from Help > Toggle Developer Tools > Console, plus any Network errors

I can see the Event Viewer screenshot with the network diagnostics results. These logs show the diagnostics ran (ErrorCode 15003 is a technical code from the diagnostics process itself).

To fix ERROR_BAD_REQUEST, we’ll need to check your settings inside Cursor:

  1. Settings > Models > API Keys:

    • Make sure “Override OpenAI Base URL” is off
    • Disable any custom API keys if they’re enabled

  2. Settings > MCP:

    • If you have any MCP servers configured, disable all of them, then restart Cursor

  3. Create a new chat:

    • Don’t reuse an existing Agent thread. Start a completely new chat and test there

Can you share screenshots of these two settings pages (Models > API Keys and MCP)? That will help us identify what’s triggering ERROR_BAD_REQUEST on your setup.

Also, please confirm whether chat works in a new window.

1- No Api keys.

3- Started new chat and worked.

4-I think the problem might be the MCPs I was using. Do you have any better suggestions for memory MCP? I am using a manifest to keep some memory for now.
