Hey, thanks for the report. The 185k token threshold is interesting since it’s close to Claude’s standard 200k context window limit. There are a few things you can try:
Quick diagnostics:
Network diagnostics: Cursor Settings → Network → Run Diagnostics (please share the results)
Try a new chat: sometimes this helps with connectivity issues
Questions to help debug:
Are you using Cursor’s subscription or your own API key (Anthropic direct / AWS Bedrock / other)?
Does the error happen with shorter conversations or different models?
Are you on a VPN or corporate network?
Let me know the diagnostic results and how your API is set up.
I am using Max Mode and my network diagnostics run all successfully on my end on http 2/1.1 and http 1 .. and i am using cursor billing.. not an external API … it happens with long conversations of many messages..
Thanks for the extra info. Could you please confirm that the request ID was captured with Privacy Mode disabled? This is important so engineering can investigate the issue.
How to get a valid request ID:
Cursor Settings → General → turn off Privacy Mode
Reproduce the error in a new chat
Chat menu (top right) → Copy Request ID
Also, please share:
Console logs: Help → Toggle Developer Tools → Console tab → take a screenshot of any errors when the issue happens again
The consistent 185k token threshold definitely needs a closer look.
