When using a temporary chat session, refreshing the browser results in a “Page Not Found” error instead of restoring the session or loading a new temporary chat interface.
Hey @Deepak_S1! That’s definitely not expected. After refreshing, it should redirect you to a new Temporary Chat screen, not a “Page Not Found.”
When you get a sec, try incognito/private browsing first, then a different browser, and clearing cache/cookies if needed. If none of that helps, please reach out to support@openai.com so they can investigate further.
I’m seeing the same issue, and I found a more specific workaround that may help narrow it down.
While continuing to use Temporary Chat, cookies named cony_key_* seem to accumulate over time. Once enough of them are stored, refreshing the Temporary Chat page starts returning HTTP ERROR 431, and after that the page keeps failing with 431 on reload.
Clearing all cookies fixes the issue, and I also confirmed that deleting only the cony_key_* cookies fixes it as well. Incognito mode also works.
So this looks like the request headers may be becoming too large because of accumulated cony_key_* cookies. My hypothesis is that the lifecycle/cleanup logic for these cookies may not be working correctly.
