Current Cursor Version (Menu → About Cursor → Copy)

v2.1.46
vscode v: 1.105.1

For AI issues: which model did you use?

Opus 4.5

Does this stop you from using Cursor

Yes - Cursor is unusable

89

Mine often starts hanging in the terminal since update

90

So, I was (Opus 4.5 was) creating a download script for me to download model files from Huggingface. I noticed that when I pasted the link and it appeared in the context as an actual clickable link instead of plain text, Opus would try to download the model file before finishing the planning step.

So be careful what you link, and if in doubt, break the link (use the unlink command).

91

The terminal is broken in the latest 2 updates. Bets to request a credit refund, until the cursor resolves the issue.

Cursor IDE

Describe the Bug

In last few days the model responses in the agentic mode became very slow (Opus 4.5, Sonnet 4.5, etc). It takes forever in “Plannin next steps”. I restarted Cursor also checked other IDEs like Antigravity, so there are no issues with my connection, etc.

Steps to Reproduce

Just run request in teh agent window

These past few days, Cursor has been constantly getting stuck at [Planning next moves] and can’t work properly.

Thanks, I’ll try this out. However, for a company with the US$ 2.3 billion funding round, Cursor is pretty slow to fix the production issues. I’m not even talking about introducing this problem in the first place, which shows lack of proper QA processes on their side

Hey, thanks for the reports. We’ve seen a few similar cases in the last few days, and the team is working on a fix.

We need:

  • 2-3 Request IDs from the stuck messages (message menu > Copy Request ID). How to get them: Getting a Request ID | Cursor Docs
  • Screenshot of Settings > Network > Run Diagnostics
  • Screenshot of errors from Help > Toggle Developer Tools > Console while it’s stuck
  • Indexing status and whether MCP is enabled in Settings (temporarily disable)

Quick checks:

  • Settings Cmd+, > search “HTTP/2” > enable “Disable HTTP/2”, then restart Cursor
  • Launch without extensions: cursor --disable-extensions, open an empty folder, then test the Agent
  • Disable MCP servers if present
  • Try a different model in the same chat

Related threads and fixes:

Please share the data above to speed up the investigation.

For now I have one.

I switched MCPs on and off so I do not see it’s affecting the problem

Thanks for the details. I see:

  • Diagnosis: SSE is being buffered by a proxy - this is a common cause of Planning hangs

Let’s quickly narrow it down:

  1. In Settings search for HTTP/2 - enable “Disable HTTP/2” and restart Cursor
  2. Launch clean:
    • cursor --disable-extensions
    • or a temp profile: cursor --user-data-dir="TempProfile1"
      Test the Agent on an empty folder
  3. Check extensions. For many, Nx Console was the cause - remove it and restart
  4. If you use a VPN/proxy - turn it off and test with a mobile hotspot. For corporate networks see proxy and SSE requirements: https://cursor.com/docs/enterprise/network-configuration

Let me know what you find. If it reproduces in a clean profile and on a hotspot, I’ll pass it to engineering.

For the past two days, the service has become extremely slow. All AI agents are responding much slower than usual, and some tasks are taking an unusually long time to complete.

Steps to Reproduce

Send any request to an agent.

Observe the unusually slow response time compared to earlier this week.
