Support Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After updating Ubuntu 24 packages yesterday I can no longer use cursor. When I login, it shows the correct email but says I’m on a free plan. No matter how many times I log in and out, same thing. If I try to run network diagnostics it only connects to the marketplace. All other endpoints spin. Same if I change to any of the other http mides

Steps to Reproduce

Update the latest packages available for Ubuntu 24

Expected Behavior

That I can log in and work?!

Operating System

Linux

Current Cursor Version (Menu → About Cursor → Copy)

Latest update on 2.x

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. It looks like a network issue with HTTP/2 after the Ubuntu update.

Please try:

  1. In the app settings: CTRL+, → search for HTTP/2 → enable “Disable HTTP/2” → restart Cursor
  2. Sign in again and run Cursor Settings > Network > Run Diagnostics

If it doesn’t help, please send:

  • A Diagnostics screenshot showing which endpoints are spinning
  • The exact Ubuntu 24.x and Cursor versions (Menu > About Cursor > Copy)
  • Whether you use a VPN/proxy/corporate network, Zscaler/Cloudflare WARP, firewall/antivirus
  • Logs from Help > Toggle Developer Tools > Console
  • If you see errors on AI requests, the Request IDs (in chat menu > Copy Request ID)

HTTP/2 fix docs: Common Issues | Cursor Docs

Let me know if the Disable HTTP/2 toggle helped.

update after abot 20 mins of letting it sit there, it finally loaded and logged me in. but of course, the moment i go to run a prompt, nothing. check the network diagnostics, nothing connects. ctry to logout and login, smae thing says im on a free plan with buttons to upgrade.
OMG! What is going on with this once reliable application?!
