Cursor IDE
Describe the Bug
I’m trying to use Cursor’s AI chat within my office VM but it’s not able to connect. I tried doing nslookup for www.cursor.co and that works. I think it’s not able hit the .sh files or not getting routed to the correct address or DNS is not getting resolved.

Steps to Reproduce
Maybe just put it behind some proxy. Not sure.

Right now, it’s not working at all.
