Connectivity suddenly dead?

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Getting tons of connection errors all day, switching to Editor mode from Agents doesn’t work, etc. I go into network settings, stuck loading for minutes. See screenshots. I’ve tried with HTTP/2 off, no difference.

Steps to Reproduce

Never had this happen before. I changed nothing.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. From the screenshot, DNS, HTTP/2, and SSL pass the check, but API, Ping, Chat, and Agent show “Canceled” error. This means Cursor tries to connect, but the connection times out.

Version 2.2.23 on Windows - good, that’s the current version.

Try these steps in order:

  1. Disable HTTP/2: Cursor Settings > Network > find the HTTP/2 option > disable it, then restart Cursor.

  2. Clear cache manually: fully close Cursor, then open Command Prompt and run:
    rd /s /q %APPDATA%\Cursor\Cache
    rd /s /q %APPDATA%\Cursor\Code Cache

    Then restart Cursor.

  3. Try another network: if possible, test via mobile hotspot or different Wi-Fi to isolate the issue.

  4. Check firewall: make sure Windows Defender Firewall isn’t blocking Cursor - add it to exceptions.

If nothing helps, it might be an infrastructure issue on our side (rare, but happens). I’ll pass it to the team for review.

Haven’t touched a single thing about my home network. None of your suggested fixes work.

I asked my neighbor if I could connect to their network for a minute, and it connects fine. So, have you guys blocked my IP for whatever reason?

Edit: It doesn’t work perfectly fine, actually. Chat is inaccessible. What’s with this mess?

I opened a different project folder, and the problem doesn’t exist. This problem doesn’t exist either: Cannot switch from Agent to Editor layout and The chat icon (cursor icon) on the top right is missing - #11 by Hyphen

This is what worked for me (see attached). Something about this extension was causing issues. It did not, however, fix the issue with swapping from Agents to Editor mode.

Thanks for the info. I’ll pass it on to the extension developers.

thx @deanrie

hi @Hyphen. I’m sorry you’re encountering issues. We haven’t had any other SpecStory users reporting network issues as a result of running the extension but I’ve created a SpecStory issue that captures your problem: [EXTENSION] SpecStory potentially causing Cursor IDE connectivity failures · Issue #140 · specstoryai/getspecstory · GitHub

Could you comment on it with any other details about how SpecStory is impacting your use of Cursor? Does everything work if you disable SpecStory?
