Ok so my brother just got a new laptop and tried to connect to the same server as me and he was unable, then i went to my computer and tried to connect and was also unable. I had connected to this server yesterday and was working fine. I can connect to the public servers, but not this one. I don't get ping readings or users on or anything with the server. All my credentials are entered correctly and I have uninstalled and reinstalled twice with no luck. Also, it is not a server issue because others are able to connect to the same server. Please help
