Connection failed. If the problem persists, please check your internet connection or VPN

I just updated to the version below and now it doesn’t work anymore, getting the connection error all the time. I restarted my Mac, the app, logged out and in, clear the cache, and nothing. Is just broken.

Same here. After the update, all connections fail with the following message: Connection failed. If the problem persists, please check your internet connection or VPN.

Most people have this either

  • Corporate/vpn blocking access
  • Router issues (not kidding, people restarted routers and they report to be able to connect)
  • Local firewall not accepting updated app as being the same, may need re-approval for internet connections
  • … many causes possible …

I guess the Cursor team would need more info as you cant connect to their servers so they wont have logs about it.

see perhaps


I had the same problem as you until I checked “Disable Http2” and it was solved

To clarify, you may need to disable the HTTP/2 setting if that protocol is not supported in your network!

We’re hoping to add auto-detection for this in the future.

Can you clarify how to disable it? I’m using cursor and I cannot see this option anywhere.

In the tutorial, it says
You can enable this yourself in the app settings (not the Cursor settings),

But i don’t understand what that means.

I had this issue the other day. What I found was that one of the MCP servers I had added was causing the issue.

After figuring out which MCP server it was I disabled it. Then the chats started working again.

You can find the settings by pressing CMD+, (comma) to open the VSCode-style application settings. The Cursor settings page is different, hence my comment to make the distinction.

Thanks for the help!

I am currently having the same issue. Only for Anthropic models. @ntyagi @totalnomad are you seeing the same thing? Do other models work that aren’t claude? openai? deepseek?

I’m seeing the same error, but it only happens on the first attempt per each message. I’ll ask something in the chat, get the error, and then hit the “Try again” button and it works. Then it fails on my next message; I hit retry; it works. Repeat.

Same thing happened to me. Tried everything (http2, vpn, restart program, update, pc reboot, new chat, new network…) nothing worked. Came back the next day, problem gone.

the same thing is happening for me.

I tried turning it off and on, but it didn’t work out. But I got a hint from the comments above that there was a problem with the MCP server, so I checked it.
“The limit is 40 tools - some tools may not be available to the agent”
I disabled the MCP server that I am not using and the problem has been resolved.
