Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m not authorizing in IDE, and I’m getting a 404 error in the browser. Also, while I was writing a ticket and checking for updates, err__timeout popped up. The requests don’t seem to be working. Although the site opens in the browser and offers to log in

Steps to Reproduce

While in IDE, I click “Login” and it takes me to the website. I confirm my authorization there, but the following happens in the requests: it just returns 404 and nothing happens. This doesn’t happen on MacOS.

Does this stop you from using Cursor

Yes - Cursor is unusable

I couldn’t fix it for a week, but like Murphy’s Law, when you ask someone for help, everything gets fixed right away.
P.S. I fixed it this way: there was a thread about proxy, even though I only use Amnesia and nothing. I was checking IDE itself and accidentally saw that I had some kind of proxy ■■■■ in there. I removed it, and all the network diagnostics ran immediately.Although I never went there, overall, happy ending

Hey, thanks for the report. Glad you figured it out yourself - the proxy in the IDE settings often messes with login and network requests, even if VPN is off.
