when i tried to hoast a game just now it came up with a error message about 5 time saying hoast lookup canceled and when i got into the game (non dedicated) it said "network: invalid hoast"

my friend informs me he gets the hoast lookup canceled when he tried to request the servers from the lobby too!? whats wrong?!

almost anytime my server crashes it is because of this. I check the server and it shows an error message saying "Host Lookup Cancelled"

Don't know what it is but it also happens with my server
