"There were no available servers that meet your search criteria" Team Fortress 2 Issue?

Alright, I've been getting this problem for a while now.. I open up Team Fortress 2 as normal, I choose the "Start Playing Now" (or whatever it's called) option, I choose the game mode for it, I wait for it to find some good servers, down bellow it says "Servers meeting search criteria: (usually followed by a lot of servers)". I check back and I get the message "There were no available servers that meet your search criteria". How does that make sense I ask? It just told me it found a large number of servers meeting the search criteria and now it tells me there are none? And this isn't just with a specific game mode, NONE of the game modes work, they all just show the same thing (even though I obviously played on a working server using the "Browse Servers" option"). Anyone know what the deal is with this?
