Checks
- Reproduce the error and record the URL, message and time. Choose a public page that needs no login.
- Keep the network and VPN route fixed and open Guest from Chrome’s profile menu. If a browser extension provides the proxy, verify that both windows use comparable paths.
- Open the identical URL in Guest and compare whether it loads and which error appears.
- If only the regular window fails, inspect relevant site data, permissions or extensions one at a time. If both fail, compare another app and record the common error.
Interpret the result
Success in Guest points toward profile-related investigation. Several browser states changed together, so isolate the cause with individual comparisons.
