The cursor is running very slowly. Tasks that used to take 2 to 3 minutes to complete now often time out and feel laggy

Hey, the VPN error when it’s stuck on “planning next moves” is usually caused by a few things. I’ll need a bit more info to pinpoint it:

Really important to check:

  • Is Git installed? Go to Cursor Settings > Network > Run Diagnostics and share a screenshot of the results.
  • Are you using a VPN or a corporate network?
  • What’s the exact text of the “VPN xxx…” error?

Try these workarounds:

  1. Disable HTTP/2 (often fixes VPN-related timeouts):

    • Open settings.json (Ctrl+Shift+P > “Preferences: Open User Settings JSON”)
    • Add: "cursor.general.disableHttp2": true
    • Restart Cursor

  2. If Git isn’t installed, the Agent can’t run:

    • Download Redirecting…
    • During install, select “Add Git to PATH”
    • Fully restart Cursor
    • Check in cmd: git --version

  3. Check older chats. Do they work? If yes, it might be an indexing issue:

    • Cursor Settings > Indexing & Docs
    • Try temporarily disabling “Index New Folders” and “Index Repositories for Instant Grep”

  4. If you’re on VPN, try turning it off just for a quick test
