Hey, this is almost certainly a corporate proxy or firewall on your side. HTTP 303 is a redirect, and it’s not coming from our servers. Most likely, SSL inspection on your network is intercepting requests to the Cursor API.

Here’s what can help:

- Check without VPN or proxy: temporarily turn off the corporate VPN and try again. If it works, that confirms the cause.
- Ask IT to add Cursor to the bypass list (best fix): they should exclude these domains from SSL inspection:
  - `*.cursor.sh`
  - `*.cursor.com`
  - `*.anysphere.co`

- Try disabling HTTP/2: Settings → Network → HTTP/2 Compatibility Mode. Not guaranteed, but it sometimes helps with proxies.
- Run Network Diagnostics: Cursor Settings → Network → Run Diagnostics. Share a screenshot of the results, it’ll show where the connection drops.

Similar corporate network case: [An unexpected error occurred on our servers. Please try again, or contact support if the issue persists](https://forum.cursor.com/t/149909)

Let me know what you see when you test without VPN.
