Sophos console does not update

Hi! All,
"Could not establish connection with the parent library, Failed to authenticate with the server. HTTP Status Code 401 (Unauthorized).VFS 0x80040414".
I get the above error message. Can anyone help?
And on a client getting this error,
"An installation could not run successfully because a previous installation,run by Autoupdate on a Sophos product, required a reboot and that reboot has not yet been done.(80041112)".
