My server list application says this when trying to list my server. My server host is Aternos. I want to get my server promoted from your server list site, then earn some money from Buycraft donations to buy an McProHosting server and go from there. But when I try to promote my server it says
Unable to connect to server () - Server appears to be offline. It must be online to add it.0
When I try to add it, it is online. Why is this happening and how can I fix it?
