Quick Fix: Reset Cursor’s Network State

Since Cursor is running and the API is reachable but internal connections are failing, let’s reset Cursor’s cached
state:

1. Quit Cursor completely:
   killall Cursor
2. Clear Cursor’s network cache:
   rm -rf ~/Library/Application\ Support/Cursor/logs
   rm -rf ~/Library/Application\ Support/Cursor/CachedData
   rm -rf ~/Library/Application\ Support/Cursor/CachedExtensions
3. Clear DNS cache (in case SpectStory left DNS issues):
   sudo dscacheutil -flushcache
   sudo killall -HUP mDNSResponder
4. Restart Cursor

Try these steps. The “Canceled” errors suggest Cursor has cached bad connection state that a clean restart should
resolve.

Bash(sudo killall -HUP mDNSResponder)
⎿ Error: sudo: a terminal is required to read the password; either use the -S option to read from standard input or

The cache clearing worked, but the DNS commands need your password.

Next Steps:

1. Manually flush DNS cache: Open Terminal and run:
   sudo dscacheutil -flushcache
   sudo killall -HUP mDNSResponder
2. Restart Cursor: Launch Cursor again
3. Test the chat: Try using the AI chat feature

The key files we cleared:

• Logs (network connection logs)
• CachedData (cached network responses)
• CachedExtensions (extension cache)

This should reset Cursor’s network state and resolve the “Canceled” connection issues you were seeing. The SpectStory
extension likely left some cached network state that’s now cleared.

Launch Cursor and test the chat - it should work now.

Progress! The cache clearing worked:

Agent - Working (streaming successfully)
Marketplace - Working​:counterclockwise_arrows_button: Chat - Still hanging with high response times (930ms-1897ms)

The Chat service is still having issues while Agent works fine. This suggests Chat uses different API endpoints than
Agent.

Try This Fix:

Use your own API key to bypass Cursor’s chat servers entirely:

1. Go to Cursor Settings (Cmd + Shift + J)
2. Navigate to Models
3. Add your OpenAI API Key or Anthropic API Key
4. Select that model for chat instead of Cursor’s default

This will route chat requests directly to OpenAI/Anthropic, bypassing whatever network issue is affecting Cursor’s
chat servers specifically.

Alternative: Try restarting Cursor once more - the Agent connection working suggests the network reset helped, Chat
might just need another restart to pick up the changes.

The fact that Agent is working but Chat isn’t indicates this is a Cursor server-side routing issue rather than your
network configuration.

no open api needed as im on the pro plan

Perfect! You have Pro plan access to all models. I can see the issue - try this:

Switch to a Different Model:

The Chat service might be having issues with your current model. Try switching to:

1. claude-3.5-sonnet (different from the 4-sonnet you might be using)
2. gpt-4o
3. grok-code-fast-1 (often faster for chat)

Select one of these models and test the chat. Different models route through different Cursor servers, so this might
bypass whatever server-side issue is affecting your current model’s chat endpoint.

The fact that Agent works but Chat hangs suggests it’s a model-specific routing issue rather than your network.

Try grok-code-fast-1 first - it’s designed for speed and might have better routing.

now its hanging this way

Does this stop you from using Cursor

Yes - Cursor 100% unusable, theres no network connection.. the AI takes a single sentence then hangs along with all the oher network diagnostics

Can you check if this works?

Network error，agent fails to work

Hey, thanks for the report, could you try adding Cloudflare DNS in your network’s system settings? Add the address 8.8.8.8. Some users have reported that this can fix the issue.
