Hi there.
I setup a dedicated server.
It is ubuntu 16.x
I have NO iptable records, did a complete iptables flush. Then I accepted all traffic (input, forward, output).
I turned OFF firewall (sudo ufw disable).
So - ALL traffic is allowed through.
However - if I use "useSteam=true" in server.ini - then nobody can connect to my server.
If I turn it off, it works just fine. However without this on - my server wont show up in the server browser in-game.
Can you look into how you are handling steam authentication? Or possibly find a better way to list servers in-game?
I host 5-6 other gameservers for other steam games, like 7DTD, insurgency, ARK, etc. - and I have NEVER seen this issue before.
I contacted my datacenter to ensure there is no outer layer of network blocks, and they did a thorough check - nothing is being blocked. Server is listening on 27000 and 27003 like it should. As I said there are NO ports being blocked, server is 100% open allowing ALL traffic through - and it still does not work. So it is 100% an issue with how the game server handles steam auth.
I already had Dirtyredz and his crew try to help me - they seem to be the most experienced server hosts in the community - and they also said the same.
Would be great if this got a little attention!
Thanks!
