Cursor IDE

Describe the Bug

Cursor is stuck trying to build index.

I’ve tried deleting cursor, and all persisted files and hidden directories, re-installing, and even re-syncing my repo so it is a blank slate with no ignore file.

But indexing is still broken, here’s the output window contents:

that message just repeats forever and no progress is made

Steps to Reproduce

Delete index, and try to rebuild it?

Expected Behavior

This should make some progress, even is slow.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. The logs show Cursor is trying to copy an index from a similar codebase but gets stuck at 0% during initialization.

Please try:

  1. Check the network: Cursor Settings > Network > Run Diagnostics and share the results. Corporate networks/proxies can block the HTTP/2 connections needed for indexing.

  2. Try HTTP/1.1 fallback: In settings, search for HTTP/2 and enable “Disable HTTP/2” to see if it helps.

  3. Clear the existing codebase: Cursor Settings > Indexing & Docs > delete the codebase index, then reopen your project to force a fresh index (not a copy).

If the issue persists after these steps, I’ll escalate it to the team, as there may be a backend issue with copying between codebases.
