I had tried all the comments above and still the issue persist for me, I’ve updated to the latest version 0.49.5 also I tried older versions like 0.47.7 but still no luck since Yesterday.
Here’s a couple of request IDs:

I’ve been experiencing the same issue for about a week now. What’s the point of paying for a subscription if these problems persist?
The error I’m getting is:
Connection failed. If the problem persists, please check your internet connection or VPN.

I completely understand how challenging it must be to provide enough resources and maintain stability as the user base grows. However, I do feel that the overall experience has been steadily declining, and as a subscriber, it doesn’t feel fair to pay for a service that no longer maintains its previous quality standards.
I hope the team can address these issues soon. Thank you for your hard work and dedication to improving Cursor
try a new chat
I was able to get past the “Connection failed. If the problem persists, please check your internet connection or VPN.” Login to the site and go to your profile. Remove your active session. Then in cursor, open a chat window and click New Chat at the bottom right. This will prompt a new login.
63N!U$ (worked! thx man)
Disable Http2 & restart computor will work.
I am able to reproduce this currently on three different laptops with two different accounts, both pro: it starts and doesn’t go when context reaches some limits. Fixable in my case every single time with starting a new chat. So either fixing this, or being able to start new chat before Cursor decides I should be able to do it would be awesome.
When cursor crashes and reopen, I get the Connection Failed message.
I go to the HTTP2 setting (I uncheck it (I previously disabled HTTP2), wait 3 seconds, then I check it again).
Prompt works again.
I disabled HTTP/2 and tried using the new chat feature again, and it worked! So if anyone else is facing issues, definitely give the solution a shot. I hope this helps!
The only solution is the chat with your model gets old or maybe too many messages then that starts to happen. Starting a new chat in new tab then problem solved.
This was the only thing that worked for me!
I encountered the same issue, but the problem persisted even after disabling http2. After wasting over 50 requests, I realized the issue might be due to the excessive content in the file that needed modification (even though I had set a longer context for the cursor). After splitting some of the code into another file, I was able to modify the file normally. It wasn’t caused by a network issue.
You are a saviour. This solution worked immediately
I’m also still getting the same issue even after disabling http2 and I have no mcp. It works for easy request that dont require online research, and works on single files but it wont work on whole projects. I get this error: Connection failed. If the problem persists, please check your internet connection or VPN
(Request ID: 86b30bd5-5309-4e87-8f11-0512fabbd506). Also on an organization VPN.
thank u so much 
I restarted my computer and router and it fixed it
Same here. I’m not using a VPN or company network, and disabling http2 doesn’t help at all. It just occurs randomly. However, if I close Cursor and start it again, I can send out my prompt again. I think it’s more of a internal issue of Cursor, not network issue.
Same here. In the last two days, I had the issue two times. I’m not using VPN, PROXY or any company firewall settings. I’m in my personal home internet, everything works perfect except Cursor. Never had an issue with Windsurf
thank you
