Unhandled exception during update exhausted all hosts, error message

[synthetic3 1]

Hey guys i apologise if this has previously been discussed but I can't find a solution anywhere else.

When using Six launcher to update DayZ it simply refuses to update. it gets stuck at 0% on verifying before an error message that reads 'Unhandled exception during Update, Exhausted all hosts' pops up. I have used this method on other computers without a problem but this simply refuses to update, it seems to go through all the mirrors but can't download from any of them. I'm running ARMA and operation Arrowhead through steam and as I've said its worked before, any suggestions? Tried reinstalling and all that, it doesn't work.

did you try updating with 6 updater instead of 6 launcher? dayz commander is alot more user friendly if your not good with computers
