What issue are you seeing?

In the ChatGPT desktop app on macOS, sending a message fails with:

Request failed with status 429

The failure is not limited to one Project. It occurs in:

• chats inside a Project; and
• projectless / ordinary chats.

At the same time, the same account remains usable on chatgpt.com in the browser and messages can be sent there normally.

The desktop app feedback upload succeeded with this Feedback ID:

no-active-thread-01a001b9-6d60-74c2-9ab0-ac0272d52aa3

What steps can reproduce the bug?

1. Open the ChatGPT desktop app on macOS.
2. Open any chat, either inside a Project or projectless.
3. Send a message.
4. The app returns Request failed with status 429.
5. Open chatgpt.com with the same account and send a message there.
6. The browser works normally.

What is the expected behavior?

Messages should send normally in the macOS desktop app, including both Project and projectless chats.

Additional information

The app had been working normally after the Aug 13, 2026 update. This failure did not start immediately after the update; it first appeared on Aug 14, 2026 during the current occurrence, around 3:27–3:29 PM America/New_York.

A screenshot was captured showing the exact error and feedback ID. The screenshot is not attached because it contains private Project names.

This is not the same reported issue as #37518.

#37518 was opened on Aug. 8, 2026 and reports a sidebar/refocus problem that began after an Aug. 7 app update: returning focus to the app reloads the conversation sidebar and produces repeated conversation-list 429 responses.

This issue began separately on Aug. 14, 2026 at about 3:27–3:29 PM America/New_York. ChatGPT desktop 26.810.41047, released Aug. 13, 2026, had been working normally after that update until this failure suddenly started. The observed failure here is that sending any message returns Request failed with status 429 in both Project and projectless chats, while the same account continues to send messages normally on chatgpt.com.
