I am trying to add Left 4 Dead servers at 220.127.116.11:27015, 18.104.22.168:27016, and 22.214.171.124:27017. The dialog box is constantly giving me an error though "STAERR001a. Try again later". I also see that there are no servers when I click the server lists. Is there something wrong with the masterserver?
Would a moderator or administrator be able to add these three servers to the server list manually?
