Describe the bug

The PriceDataReload component (ui/litellm-dashboard/src/components/price_data_reload.tsx) polls two admin endpoints every 30 seconds via setInterval:

• GET /schedule/model_cost_map_reload/status
• GET /model/cost_map/source

It authenticates using accessToken = decoded?.key extracted from the JWT cookie. When a user's virtual key expires, the JWT cookie itself may still be valid (the user stays logged in), but every polling request hits user_api_key_auth which raises:

ProxyException: Authentication Error - Expired Key

This produces continuous HTTP 400 errors in the server logs every 30 seconds, indefinitely, until the user manually refreshes the browser — even though the page appears to function normally.

Reproduction

1. Open the Admin UI → Models & Endpoints → Price Data Reload tab
2. Leave the browser tab open with an expired virtual key
3. Observe repeated LiteLLM Proxy:ERROR auth_exception_handler.py:78 - user_api_key_auth(): Exception occured in pod logs every ~30 seconds

Expected behavior

When the polling requests receive HTTP 400/401 (auth failure), the interval should stop. The UI should show a message prompting the user to re-login rather than silently continuing to spam the server.

Root cause

In price_data_reload.tsx, the useEffect starts an interval but never checks whether API calls return auth errors:

const interval = setInterval(() => {
  fetchReloadStatus();   // throws on HTTP 400, but catch block doesn't stop the interval
  fetchSourceInfo();
}, 30000);

The catch blocks log the error and set default state but do not clear the interval.

Fix

A fix has been submitted in PR #XXXX. Summary:

• Extract isAuthError() helper to detect HTTP 400/401 responses
• Wrap fetchReloadStatus / fetchSourceInfo with useCallback
• On auth error, call stopPolling() which clears the interval and sets pollingDisabled = true
• Show an <Alert> banner when polling is paused, prompting re-login
• useEffect depends on pollingDisabled so it restarts correctly after fresh login

LiteLLM Version

Reproducible on current main (c89496f).

Environment

• Deployment: Kubernetes (LiteLLM Proxy)
• UI accessed via Admin Dashboard
• Virtual key with expiry set
