Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report with the Request IDs and logs.

This is a known bug on our side. In long chat sessions, the request to the provider is built incorrectly, which causes an error. The client shows a generic message like “Unable to reach the model provider”, but the issue isn’t your connection.

As a workaround, start a new chat session using Cmd+N or via the menu. It only shows up in long sessions with lots of messages.

The team is aware, and your report helps us prioritize it. Let me know if the workaround helped.

Nick_Maris · April 14, 2026, 1:47pm

Thanks, it does work in a new session. A more descriptive error message would help.

Nick_Maris · April 14, 2026, 1:51pm

Well, now cannot have a converation as every message needs a new session in order to work.

Nick_Maris · April 15, 2026, 8:47am

Somehow after a few sessions of one message long, it now works, thanks.
