Problem with proxy

You may get this error in conjunction with accessing the Internet via a proxy server, please ensure the address is valid in Internet Explorer > Tools Options > Connections > LAN Settings.

  • If you do not have, or are unaware of, a proxy server, please ensure that the only box checked off is Automatically Detect Settings, and that the proxy information within the host is removed.
  • If you do use a proxy, the address and port info should be correct in IE, and match in the host. To check the proxy settings in the host, please click the host tray icon and select LogMeIn Control Panel. When the window opens, click Options > Preferences > Advanced Tab. Scroll down to the Proxy Settings and confirm the proxy server address & port.
