I have just recently made an account and tried to stream the server. I have used the Rcon method and inputted all the commands you have listed in the exact order and from what I can see it should be working. It's just when I put the IP to see whether the server is streaming or not it says that the server has'nt been added etc.
It was streaming a month back though, and I am just wondering if it has been deactivated? Also, does the streaming take time to update, or should after inputting all the commands it should say that the server is streaming on this site?
Thanks for your help. :)
