Cannot connect to VAC2 secured servers :/

[Unfocused]

"A connection to Steam VAC2 servers could not be made (...)"

This is what I get. I haven't changed anything in my connection setup (including firewall etc.) since yesterday, when I could play just fine.

Solutions anyone?

yeah, its a VAC bug. Alfred knows about it, and they are working on it
