Have u tried the manual update that agaito put in the patch description? O-O
It's caused by your anti-virus, there was a patcher update and your anti-virus for some reason is blocking the patcher from connecting to the internet. So please recheck if the patcher.exe is added to your anti-virus exception list. Also check if disabling the anti-virus helps (this seems to not work always) If it fails, manual update should work
Update server connection fails error should not prevent from being able to log in the game. Please check if you can log in directly via elementclient located in EPW /element folder (just run that file)
