When you save the Scanner proxy configuration, you see the error "The proxy server connection has not been established. Please check if the proxy server is configured correctly in case this happens constantly."
Release : 10.7
Component : Default-Sym
Saving the proxy configuration will attempt to connect to Broadcom spam definition servers to verify the configuration. If the connection fails, the above error is the result.
Confirm the proxy settings and investigate the proxy and any network filtering that might interfere with the communication.
