Codebase Indexing Loading, Slow Responses

Bug Reports
1

Codebase indexing is stuck on “Loading…” and AI responses are taking up to two minutes. It’s not due to slow requests, I have over 300 fast ones left. Disabling HTTP/2, as the docs suggest, made no difference. I have formatted my machine, I also completely uninstalled cursor deleting all the folders and files… obviously no fix. A recent response took 1:29 on “generating” and then stopped without any output. This makes the app unusable and incredibly frustrating.

Other users have reported similar problems, but no one has found a solution yet. Some mentioned receiving “handshake failed” errors, which I was experiencing earlier too. Now it’s back to displaying “Loading…” continuously without progress.

The really strange thing is I tested it on my wife’s laptop using our same home network and it works fine there!

I uploaded a video on Google Drive to demonstrate the codebase indexing stuck on loading and also the slow AI response: video link

basically unusable. Cursor status page still shows everything is fine?

Maybe this is helpful to the cursor team:

Update

It’s working now. Not sure what changed, maybe the Cursor team fixed something, or something else happened. The only thing I did differently was install the latest Visual C++ Redistributable.
