Support Help

Hello,

I have an ongoing issue with Connection failed msg. Every time I restart the program or change the agent it keeps on happening after running a code for a few minutes.

Hey, thanks for the report.

I can see screenshots with the “Connection failed” error. This is usually related to network settings, extension conflicts, or MCP servers. Let’s try a few things:

  1. Disable HTTP/2:
  • Press CTRL/CMD+, to open Settings
  • Search for “HTTP/2”
  • Enable “Disable HTTP/2”
  • Restart Cursor
  1. Check MCP servers:
  • Cursor Settings > Features > MCP Servers
  • Try temporarily disabling all MCP servers
  • Restart and check if the agent works
  1. Check extensions:
  • Start Cursor with extensions disabled: cursor --disable-extensions
  • If it works, disable extensions one by one to find the problematic one
  1. Collect diagnostics:
  • Cursor Settings > Network > Run Diagnostics: screenshot the results
  • Help > Toggle Developer Tools > Console: screenshot any red errors after reproducing the issue
  • Copy 2 to 3 Request IDs after the error (chat menu > Copy Request ID)
  1. Extra info:
  • What’s your region or country?
  • Are you using a VPN or proxy?
  • Cursor version? (Help > About Cursor > Copy)
  • Which extensions and MCP servers are installed?

Similar thread with possible fixes:

Try the steps above and let me know what you find.

Hello Rie,

thank you for the prompt response, the issue is fixed, instead of using AUTO agent, I am selecting a specific one for the jobs at hand, and Opus 4.5 runs without any hiccups. But I am perplexed as to why this issue only happens when I get AUTO agent.

Best Regards,
Sebastian

I am on win11. Tried disabling https/2, disabling all extension, no mcp, restart Cursor with “cursor --disable-extensions” still happens.

Diagnostic all green!

Model is not on “auto” though this shouldn’t matter.

Tried new chat window as well, doesn’t help.
