Additional Information

I have logged out and back in, started a new agent chat, set HTTP compatibility mode to HTTP/1.1, disabled privacy mode, changed networks, ran network diagnostics (which turned up nothing), restarted the app, checked the status of Cursor and ChatGPT’s API, and disabled my VPN. I also checked for notifications on agent limits in the IDE and on my dashboard, and did not see any. I only began experiencing this issue today, after updating to the latest version of Cursor.

Does this stop you from using Cursor

Yes - Cursor is unusable

Update: Cursor now works, but only with the VPN? I set my location to Denmark (I’m in Cambodia). Before disabling the VPN, I also had my location set to Denmark, so I am not sure what is happening here.

Hey, thanks for the report.

This is an unusual situation. Usually a VPN causes issues with Cursor, but for you it’s the opposite. This looks like your ISP blocking something, or regional restrictions on access to Cursor’s API.

A couple quick questions to narrow it down:

  1. Without the VPN, do other Cursor features work? (Tab autocomplete, Inline Edit, regular Chat without Agent mode)
  2. Without the VPN, can you try a different model, like Claude Opus 4.5 or GPT-5.2 Fast. Do you get the same error?

It seems your ISP might be filtering or blocking certain Cursor endpoints. The VPN gets around that by routing through different servers.

For now, as a workaround, please keep using the VPN.

Hello Dean,

None of these features or models work without the VPN. I also tested Gemini 3 Flash, which does not work as well.

I will also mention that most VPN protocols are also non-functional right now for me. I have to configure my system and VPN very specifically to maintain a normal connection to the internet.
