Error updating signature file

[Guest]

I get "Failed to connect to server. Error: 0x800706BA" from Application Event
Viewer from MsiInstall
And I get
"Installation Successful: Windows successfully installed the following
update: Definition Update 1.13.1276.16 for BETA Windows Defender (KB892519)"

Bet still Automtic update tries to Install 1.13.1276.16 and if I confirm I
get the first line error
