Composer 2 fails with "We are having difficulties reaching the AI provider. Retrying automatically..."

Where does the bug appear (feature/product)?

Background Agent (GitHub, Slack, Web, Linear)

Describe the Bug

Hi Cursor team,

I can’t use Composer 2 anymore. In agent chat I keep getting:
“We are having difficulties reaching the AI provider. Retrying automatically…”
This started early in the morning today. It happens every time, on all projects.

Steps to Reproduce

Open Cursor IDE
Open agent chat / Composer 2
Send a normal prompt
The message appears: “We are having difficulties reaching the AI provider. Retrying automatically…”

Expected Behavior

Composer 2 should respond normally.

Operating System

For AI issues: which model did you use?

Composer 2 (agent chat, auto-selected model)

For AI issues: add Request ID with privacy disabled

composer-2

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor
