I was able to get through all of the steps alright, but when I tried to host a server, no one joined. I opened up Blockland a second time (very laggy though), and then checked the list of servers. Mine was there, but under Ping it said 'dead' (by the way, what does 'ping' mean?).
Is this supposed to happen since it was my own server on my own computer, or do I have to make some adjustment?
