Error: No Connect transport provider registered

Bug Report

I have been unable to get cursor functionalities working for a few hours now.

Upon inspection in the Window output I notice the following error.

2024-10-16 21:22:16.095 [error] No Connect transport provider registered.: Error: No Connect transport provider registered

Is there anything I can do to resolve this?

Hey, this seems like some weird logs. Are you running any extensions or anything that may have an impact on your Cursor install?

As a simple first attempt, could you try a clean reinstall of Cursor, ensuring you’ve got the latest version from the website, and see if you still face this?

Thanks

The issue also occurs on a clean install.

I uninstalled cursor via Windows settings & deleted the ~/.cursor folder.

This is the full Window output when I start cursor. My guess would be that this Error: No commit search provider registered is related to the other issue.

Hi, thanks for the info. Sorry you’re having issues getting up and running.

Can you try launching Cursor, and seeing if it shows up in task manager (even as a background process)? It’s possible Cursor is trying to launch, something is going wrong but it gets stuck, neither crashing or working correctly.

Do you get any visible errors, and do you ever see the Cursor window or does it just never fire up?

Thank you for the help so far in getting this working.

Cursor is starting just fine. I can use it as an IDE but any and all AI related functions are not working.

The console shows the following (similar) error:

The errors only occur after I try to use chat/composer/inline AI functions. Cursor Tab also does not seem to be running as there are no suggestions.

Another thing that I notice which may be related to the issue is that it is SPAMMING login polls non-stop 5/second after I log in. Login is succesful as I can see a proper token response in the devtools.

8

Are you using a VPN, Zscaler, firewall, or any other software that could be blocking your connection?

9

Not that I am aware of.

Additionally all requests using a browser to the urls I was able to locate in my debug session (stuff.cursor.sh) came through just fine.

I did perform two other tests, succesfully:

  1. I created a new windows account and installed cursor. Ctrl+K “html hello world” worked this time.
  2. Then, I created a new vscode/cursor profile on my original windows account and tried the same. This also works.

Therefore, it seems that something, somehow, corrupted my vscode profile. So now I am looking into this.

10

Ah okay, that’s a good start.

Do you have any VPN or firewall in the way that could cause issues with Cursor connecting to its backend server, as that’s a common cause for the AI features to fail?

If not, we’ll see what we can do.

11

I had the issues at home without any firewalls, so I do not think this can be the issue.

Additionally, a clean profile seems to work from the same current network/device, so that is another indication that VPN/firewall is not the issue.

Let me know waht information you need.

I didn’t see @deanrie had already asked about a VPN, apologies.

It does seem that either a previous/existing VSCode installation or Cursor has broken something in your current Windows profile. My best bet would be to use something like Revo Uninstaller to remove both Cursor and VSCode then try a fresh install.

Both apps use some shared resources, and even after an uninstall can leave some stuff behind. An app like Revo will clean everything up so it’s a much closer to a fresh install.

Revo offers a portable, free version that doesn’t require an install, and I have used it before for similar purposes, but is just a personal suggestion and isn’t verified or endorsed by Cursor.

In the end I chose to run with a new vscode profile. I suppose this is similar to a clean installation.

I have not found the trigger for this broken state.

Glad you’re all sorted!
