Hey, is your internet connection okay? Are you possibly using a VPN or proxy? Also, run a network diagnostic by opening the settings and going to the network tab.

Thank you so for the advice!!! I’ve been using cursor for about 4 months without too many issues, and just got the $200 plan yesterday morning. I ran the dianostics and got some errors associated with HTTP/2.

I changed to HTTP/1,1, diagnostics cleared, continued the conversation, and the agent got hung up again, I refreshed the net diag and they cleared,stoped the agent, prompted please continue again,

and now my prompts is simply returned and not submitted, abd the network diagnostics are hung up with just about everything cancelled

Then moved to a new chat, my first prompt went fine, and the second prompt was rejected again with network diagnitics failing and hung up again.
