Hey all, I've just started to host a server which I created through Nitrado. I forwarded the relevant ports on my router and everything seems fine. My son can join through the ark friends servers list but not through steam as when he tries to add the address it just says "server not responding" My question is how can I get it to show on the steam server list (it's been active for 3 hours now) and do I have to be online for him to join my server or can he play alone. Would my pc have to be left on to allow him to use my server. Thanks in advance.
