I put Gmod as the Test of Time award , but Terraria definitely got the Five more minutes aware for me . Gmod is a game I always come back to more than Terraria , but when I do come back to Terraria , I end up playing for far , far longer than I intend to . <| sep |> Congrats on the wedding .

His shouts are too strong . <| sep |> I haven ' t been boosting for it so yeah I don ' t have it lol <| sep |> Is your headless client running on a different PC ? If so . have you added the ip of the other PC in your server . cfg ? headlessClients 127 . 0 . 0 . 1 , 192 . 168 . x . x localClient If not add the above to the last line of your server . cfg , like you normally do , but , where the last part is the ip address of a lan computer you may be using for the HC . Assuming you have sorted that already . I would check what Crazy said , there is no need for a config for the HC . I normally run my server on a linux box . I am not sure why you have an exit at the end ? Try without the exit , that may leave the cmd promt open to help debug . plus try localhost or 127 . 0 . 0 . 1 instead of an ip address when you start your server and HC if its on the same computer .
