Facing Grep Attempted, Read Attempted, Time outs, EventStreamFailed etc

Deepak_Mehrotra · February 10, 2026, 10:05am

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m experiencing very frequent timeouts/failed attempts—essentially on every chat. It usually requires reloading the window multiple times just to get the agent running, and even when it does start, the issue often reappears midway through tasks.

I’ve already tried all the troubleshooting steps suggested in the support channel, including:

Reinstalling Cursor (to latest ide)

Switching between HTTP/2 and HTTP/1.1

Turning VPN on/off

Unfortunately, none of these have helped.

This has been happening consistently for about a month now and is seriously impacting my day-to-day work. At this point I’m effectively unable to code or use agents reliably.

Can someone please help me diagnose and fix this?

these are my cursor ide details –

For AI issues: which model did you use?

claude opus/sonnet

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This looks like it could be related to a known agent timeout issue the team is tracking. Since you’ve already tried the usual fixes (reinstalling, toggling HTTP/2, VPN), let’s dig deeper.

I need a few things from you:

Request ID: next time the error shows up, open the chat context menu (top right of the chat panel) and click “Copy Request ID”. Paste it here.
Console logs: go to “Help > Toggle Developer Tools > Console”, then reproduce the error. Copy any red errors you see.
Network environment: are you using a corporate proxy (like Zscaler or similar) on your network? This class of errors (especially “Grep Attempted”, “Read Attempted”) is sometimes caused by a proxy or firewall that intercepts the agent tool call streams.
Project size: roughly how many files? Does this happen in all projects, or only a specific one?

Also worth trying, if you haven’t yet:

Run cursor --disable-extensions from Terminal to rule out extension conflicts
Run network diagnostics: Cursor Settings > Network > Run Diagnostics
Clear workspace state: fully close Cursor, then delete ~/Library/Application Support/Cursor/User/workspaceStorage (make a backup, the folder will be recreated on restart)

This diagnostic info will help narrow it down to either a network or proxy issue, or a host extension timeout bug.

Network environment – Yes we use ZScaler here

It’s a monorepo having all services at one place… but I have been using cursor for a lot while now and till the time before a month or so (~8-9 months)… this issue didn’t occur so frequently on this monorepo code

@deanrie — just checking if there’s any resolution update on this issue of mine?

Hey @Deepak_Mehrotra thanks for the follow-up and for the detailed logs. They’re really helpful.

From the console output, the root cause looks clear: the Extension Host stops responding, which then triggers a cascade of Agent Stream Start Failed and deadline_exceeded. A few things stand out:

You’re using SSH Remote ssh-remote+emdeepak-godev.devpod-ind. Agent tool calls like grep, read, and so on go through an SSH tunnel to the remote host. With Zscaler in the path, that adds noticeable latency, which can push the Extension Host past its timeout threshold.
Heavy extensions. I can see Uber.vscode-dev-portal, Anthropic.claude-code, Jupyter, and a few others loading on the remote side. Any of these can slow down the Extension Host response.

Here’s what I suggest trying, in order:

A) Test locally first. Open a small local project (no SSH) and run a couple of agent chats. If everything is fine locally, that confirms it’s related to SSH Remote plus the network.

B) Run with extensions disabled:

cursor --disable-extensions

If the agent works over SSH with no extensions, then re-enable them in batches to find the culprit. Start by disabling Anthropic.claude-code and Uber.vscode-dev-portal since they register extra views and services in the Extension Host.

C) Run network diagnostics: Cursor Settings > Network > Run Diagnostics. Share the results here.

D) Clear workspace state (make a backup first):

Fully quit Cursor
Delete ~/Library/Application Support/Cursor/User/workspaceStorage
Restart

The team is aware of Extension Host timeout issues in this setup and is investigating.

Let me know what you find, especially from steps A and B.
