Strange chat conversation

Bug Reports

Describe the Bug

For some reason, I use a VPN to access the internet.

When I use agent mode, I chat with the AI.
Suddenly, the AI could no longer connect, and it displayed:
Connection failed. If the problem persists, please check your internet connection or VPN
aborted [aborted]
Request ID: 78830145-4542-4bdf-892b-cbe797b4bff1

After that, no matter what I sent in this specific chat conversation, the connection would fail.
However, when I started a new chat, everything worked fine again.

This is very strange. Is there some kind of limit on a single chat conversation?

Steps to Reproduce

This has happened many times, and I’m not sure how to reproduce it.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, does creating a new chat resolve the issue?

Yes, starting a new conversation makes everything work perfectly, and the AI even remembers the content of the previous conversation. I don’t quite understand the principle behind this, but isn’t it a bit amazing?

I think this happened because of switching models within a single chat, or your chat has existed for too long. In any case, could you share the request ID? For this, you need to disable privacy mode if it’s enabled, then reproduce the issue when it happens again and copy the ID.
