Authentication failed

Error message

Authentication failed

What it means

Synchronous (requests-based) Bing/Copilot conversation creation failed: after trying the configured BING_PROXY_URL (default https://edgeservices.bing.com/edgesvc/turing/conversation/create) and the fallback proxy edge.churchless.tech, the HTTP status was still not 200, so edge_gpt_free raises Exception('Authentication failed'). The printed status code/body/url above the raise identify the actual response.

Solutions

1. Check the printed status code and response body — 401/403 means cookies/beta, 429 means rate limit or IP block
2. Provide fresh valid Bing cookies to the conversation client (the newbing bridge passes cookies; stale cookies are the #1 cause)
3. If self-hosting BING_PROXY_URL, verify that proxy is alive and forwards cookies correctly; otherwise clear the env var to use the default + fallback
4. Switch to a supported model/bridge (this free endpoint is inherently unreliable) or retry later when the fallback proxy recovers

Example fix

# before
os.environ.pop('BING_PROXY_URL', None)  # both bing + churchless return non-200

# after: supply valid cookies via the newbing bridge config
# config_private.py
NEWBING_COOKIES = '...fresh _U cookie from edge browser...'

import requests
for url in (os.environ.get('BING_PROXY_URL') or 'https://edgeservices.bing.com/edgesvc/turing/conversation/create',
            'https://edge.churchless.tech/edgesvc/turing/conversation/create'):
    r = requests.get(url, timeout=10)
    print(url, r.status_code)  # both must be 200 for the free bridge to work

for attempt in range(2):
    try:
        convo = _Conversation(sync_mode=True, cookies=cookies)
        break
    except Exception as e:
        if 'Authentication failed' in str(e) and attempt == 0:
            cookies = refresh_bing_cookies()
            continue
        raise

When it happens

Trigger: _Conversation.__init__ path in request_llms/edge_gpt_free.py:341: both conversation/create GETs return non-200. Typical when Bing rejects the client cookies (missing/invalid edge cookies), the beta is not enabled for the account, an IP is blocked (429/403), or the churchless fallback proxy is down.

Common situations: Using the free newbing/edge_gpt_free bridge without valid Bing cookies; region/IP blocked by edgeservices.bing.com; both endpoints rate-limited; BING_PROXY_URL pointing at a dead self-hosted proxy.
