Update web page context failed

Error message

Update web page context failed

What it means

ChatHub handshake failure: before streaming a prompt, _ChatHub.ask sends a web-context update POST to conversation/create-style endpoint carrying the page context/conversation signature; a non-200 response triggers Exception('Update web page context failed'). Printed status/body/url identify the rejection.

Solutions

1. Create a fresh conversation (new cookies/signature) instead of reusing a long-lived one
2. Check printed status: 401/403 → refresh cookies; 429 → back off and retry later
3. Verify BING_PROXY_URL forwards the context-update endpoint, not just conversation/create
4. Catch this exception and auto-recreate the conversation once before giving up

Example fix

# before
try:
    async for resp in chathub.ask(prompt):
        ...
except Exception:
    raise

# after: recreate conversation once on handshake failure
try:
    async for resp in chathub.ask(prompt):
        ...
except Exception as e:
    if 'Update web page context failed' in str(e):
        chatbot = await Chatbot.create(cookies=COOKIES, proxy=PROXY)  # fresh signature
        async for resp in chatbot.ask(prompt):
            ...

import time
if conversation.created_at and time.time() - conversation.created_at > 15*60:
    conversation = await Chatbot.create(cookies=COOKIES, proxy=PROXY)  # refresh before signature expires

try:
    async for resp in chathub.ask(prompt):
        ...
except Exception as e:
    if 'Update web page context failed' in str(e):
        chatbot = await Chatbot.create(cookies=COOKIES, proxy=PROXY)  # fresh conversation, one retry
        async for resp in chatbot.ask(prompt):
            ...
    else:
        raise

When it happens

Trigger: request_llms/edge_gpt_free.py:508: the initial context-update request in ask() returns non-200 — expired or invalid conversationSignature/conversationId, rate-limited IP, or the (proxy) endpoint rejecting the payload shape. It fires per-message, so a session can work once then fail after signature expiry.

Common situations: Reusing a conversation object after its signature expired (~minutes); heavy usage triggering 429; cookies partially valid (create succeeded, chat rejected); churchless fallback proxy restrictive on the context update call.
