What does Proxy server mean?
A proxy handles supported requests on behalf of a client. Applications may use a system proxy, their own proxy configuration or neither. A stale proxy setting can therefore affect one app differently from another on the same computer or network.
Why it matters
A proxy is not the same as DNS resolution or necessarily the same as a VPN. An unknown public proxy can expose request information and may handle media poorly. Use only an authorised documented arrangement, especially on work or school equipment. If a previous test left a proxy enabled, restore the intended configuration through the operating system's supported controls and compare the original failed operation.
