Connection Error: "Unable to reach the model provider" (Network Diagnostics Clear)

Describe the Bug

I am consistently encountering an error message stating “We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.” when attempting to use Cursor’s Agent functionalities using the “Auto” modal. Despite the error message, Cursor’s internal “Network Diagnostics” report that all connections (DNS, HTTPS, HTTP/2, SSL, API, Ping, Chat, Agent, Marketplace) are functioning correctly and show “Good” status.

Steps to Reproduce

Open Cursor.

Attempt to interact with Agent mode using “Auto” modal.

Observe the error message: “We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.”
