Yunbao VPNSeparate network recovery from tunnel recovery
After waking, wait for Wi-Fi or Ethernet to recover and test ordinary connectivity before inspecting the VPN. A running app does not prove its tunnel is active. Record whether failure occurs only after sleep rather than treating it as an all-day route fault.
Reconnect through the interface you use
Reconnect Yunbao through its official client. For a manually configured Windows VPN, select its profile under Network and Internet/VPN. Do not mix profiles or guess servers, protocols and credentials; manual details must come from the provider.
Retest a complete sleep cycle
After connecting, load a familiar page, save work, then test sleep and wake. Record network recovery, app state and access results. If reproducible on one network only, investigate that network; involve administrators on managed PCs. Disabling sleep or the firewall is not the default fix.
