Agent sometimes doesn't respond

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m on Linux. The major longstanding issues have been fixed (kudos!). However, as of a few versions ago, I get occasional non-responsiveness from the agent after writing. The 3 dots will animate as if stuff is happening, but nothing happens. I wait and wait. I press the stop button and send the message again. Sometimes I can make it work again by cloning the chat, but often it doesn’t work.

Steps to Reproduce

It’s seemingly random, so it’s hard to reproduce. But after a few interactions, the agent just won’t do anything.

It happens with any AI

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

hi @yotambarnoy and thank you for the bug report. For cases where agent does not respond could you share following info so we can see clearer what the cause could be:

  • Check Settings > Network > Run Diagnostic and report any errors shown there.
  • Errors from Help > Toggle Developer Tools > Console

No errors in network diagnostics. I already posted 2 console logs above.

Similar issue here. Since around 1.7.37 (currently on 1.7.39) when I use grok-code-fast-1 I get just “…” and it is stuck forever. Stop/start the chat does not help. I restart Cursor and then run the same chat again, then it asks me to log in for suspicious activity, I log in and start the LLM request again and it works. Happens 5-10 times a day, usually when I pause my work for a while.

I’m on Debian 12, KDE, Cursor appimage 1.7.39, dual monitor with 2 Cursor windows: 1 for each of my projects/workspaces. Latest problematic request ID: 1b1f7ddc-cce7-4de0-8862-0da0785bfd7f

2 issues

  1. Instead of “…” - the Log In pop-up window should show - and it doesn’t. It does only after a restart of Cursor.
  2. I don’t do any suspicious activity to be asked many times per day to login. That did not happen in previous (around 1.7.35) versions

This just to add that I encounter the exact same behaviour as @jivko-chobanov, yet on Mint, with cursor 1.7.39.

Cursor IDE

Describe the Bug

I send a message in chat; and the only UI update is the three dots appear and pulsate.

After closing, re-opening, re-logging in - re-sending the same message; it has been working (UI updates to “thinking …” and the agent works throught the task)

Steps to Reproduce

Intermittent - but occurs relatively frequently (once every hour?) on both Agent and Plan modes

For AI issues: which model did you use?

Feels like its before the request is sent to a mode; mostly using gpt-5

Does this stop you from using Cursor

Yes - Cursor is unusable

Fortuitously :slight_smile: it happened right after posting; it just its without making progress.
It runs much faster (<5 seconds) vs 1min + after a restart; so it does not seem like its “thinking”

im facing the exact same issue on fedora! can someone please address this asap??

Hey, thanks for the report. We’ll investigate this.

This is happening to me constantly on Mint. It’s something to do with session management. I login, then my first session works fine. But if I tab-over to some other historical session, and tab back to the session I was just in…. and send a new message, the agent gets stuck with the 3 bouncing dots forever. I have to kill Cursor every time this happens and restart it again, JUST SO I can have one run and then I get the same issue starting a new session… have to kill Cursor. Stuck in this loop now and very annoyed.

This only started happening for me after you implemented login checks.

Same here Ubuntu 24. Only thing that works is Reload window. Happens like once every 1h/1h30
