Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. We’re already seeing a few reports of connection errors when the context goes above roughly 185–200K tokens with Sonnet 4.5, and the engineering team is already investigating this.

To confirm you’re hitting the same issue, please:

Run network diagnostics: Cursor Settings → Network → Run Diagnostics and share a screenshot of the results
Test without Max Mode: try the same conversation with Max Mode disabled — does it work with regular context?
Check your network: are you using a VPN, corporate network, firewall, or antivirus?
Share console errors: Help → Toggle Developer Tools → Console tab → take a screenshot of the errors when the request fails

Once we have these extra details, I can link your case to the ongoing engineering investigation.

100% error by account. When i change account => this is fixed.

But when i returned comeback this account ([email protected] ) => continue error when context 200k.

I’m having the same problem and I have tried multiple accounts. As soon as it begins to touch the 200k level I get the error below. I don’t have a VPN and things work with Max mode disabled. As an added note it seemed to corelate with Opus 4.5 release. Here is the error log from the developer console.
