Renew IP Address and Reset TCP/IP Stack
Some websites do not allow proxy users to access their websites. So, chances are that yourIP may have been blockedor flagged, and you are facing the proxy error.

When you renew the IP, you are assigned a new address from the router using the DHCP network management protocol.
