Connection failed occurs very often, strangely when I restart cursor it goes away. So I don't think it's connection error

I’m having the same problem here. Usually, restarting the IDE fixes it, but now nothing I do seems to solve the issue.

After a few attempts, it normally starts working again on its own. However, today it fails more often than it returns a response.

Same for me. Been like this for a few days now. Waiting for support to help (going round and round in circles with ‘Sam’ the AI support assistant). I am using a standard consumer fibre broadband account on Windows 11 Pro. No VPN. All has been fine until a few days ago. No changes on my system. It started by saying no internet connection (the internet is ‘always on’ for me - very rarely ever fails). I can also load the standard VSCode and use AI’s with that no problem (and browsers and everything else internet related including writing to this forum right now, while Cursor is telling me I have no internet connection - ‘Sam’ suggested I turn off http/2, restart and try again etc. all of which showed that everything was working fine according to Network Statistics - in all modes http/1 and http/1.1 as well).
