Yunbao VPNA working browser does not prove every app works
A browser proxy is usually controlled by browser settings or an extension. A system VPN requires checking the actual connection and routing. Do not assume a proxy extension covers every application or infer VPN coverage from one webpage.
Compare one connection layer at a time
Save existing proxy settings. On a personal device, compare VPN only, proxy only and both together using the same webpage and another app. Record results for each test. Ask an administrator before changing managed proxy configurations.
Avoid ambiguous stacked settings
If failure occurs only when both are active, check the proxy destination, authorization and configuration source. Avoid adding more extensions. Manual Windows VPN profiles need correct provider details; do not guess server addresses or protocols. Follow Yunbao client prompts.
