Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a known issue. We saw the same thing with a few users last week.

Most of the time it’s caused by MCP servers or third-party API key settings that block the connection. Try this:

  1. Cursor Settings > Tools & MCP: If you have any MCP servers connected (especially Perplexity, Figma, or custom ones), temporarily disable all of them.

  2. Cursor Settings > Models: Make sure “Override OpenAI Base URL” is turned off. If you added any third-party API keys (OpenAI or Anthropic), temporarily disable those too.

  3. Sign out and sign back in (Cursor Settings > Sign Out, then Sign In).

  4. Open a new chat in a different project folder to test.

This worked for other users with the exact same issue:

If that doesn’t help, try launching Cursor from Terminal with cursor --disable-extensions to rule out extension conflicts.

Let me know how it goes.

Hi Dean,

Yes, disabling the perplexity MCP did the trick.

Hi Dean, thanks for your advice. Disabling MCP was the solution

hmm.. i have the same issue - i am a fresh user with only the basic install going on ( using local Cursor though ) for coding, with Sonnet 4.5 as the engine.
I had so many issues, first it started redoing itself, back and forth in an endlessloop, and after i forcibly stopped it, this Connection issue started - only to end up in me using my montly limit .. in 2 days …
I love what Cursor is doing for me , but i dont much enjoy that i probably lost 25% of my limit in issues …

I don’t have any MCP tools and the Override OpenAI Base URL was toggled off, but I still get this

what else to try?

I switched models, solved , no further action

11

I just tried one thing - i switched from HTTPS/2 to HTTPS/1.1 - and so far its working … ( who wanna bet im gonna jinx it now ? )

.. Settings - NETWORK - Http Compability mode ..

edit : 4 hours later, still working like a charm …

Glad to hear both of you found workarounds.

@Vidar_Halvorsen switching to HTTP/1.1 is a solid fix. If you run into this, go to Settings > Network > HTTP Compatibility Mode and switch it to HTTPS/1.1.

@Chris_Sleat glad switching models helped. If it happens again, try the HTTP/1.1 trick above too.

For anyone finding this thread later, here are the main fixes that worked:

  1. Disable MCP servers, especially Perplexity, Figma, and custom ones, in Cursor: Settings > Tools & MCP
  2. Turn off “Override OpenAI Base URL” and remove any third party API keys
  3. Switch HTTP Compatibility Mode to HTTPS/1.1 in Settings > Network
  4. Sign out and sign back in, then test in a new chat
