Hi, I'm a server admin and I've been succesfully using rf2 dedi server for months before having this problem: now for some reason the server is not visible both in steam and launcher lists, even if everything looks fine. Let me show why I am sure that this issue is not depending on config, network or anything related to the server. This is the operating server window with an event loaded and running: View attachment 20943 Of course the first thing was to triple-check firewall and in general the communications capabilities of the machine. In my firewall there's a rule for rf2 dedi executable that allows communications for any protocol on any port, but I also tested it: from my client machine (a client outside the server's LAN) I can telnet the dedi on its ports without errors: View attachment 20942 Also, server side, I can see the connection popping up: to check this I used CurrPorts, which is showing that not only dedi is listening on its ports, but also that my telnet request shown above did estabilished the connection: View attachment 20941 I made a lot of research and testing, changed configs, mods, anything: the server never appeared on mp lists. Please keep in mind that, as I said, I used to host from this very same machine without problems until some months ago (february 2016 to be precise): by then server list was still ingame (not on the launcher), and everything worked fine. Server side nothing changed since then, but I noticed that rf2 went through some updates in the meanwhile, so my current bet is that something related to the last updates could be the cause of the problem. I would be grateful to anyone who can give me a hand on this cause I'm currently out of ideas. Thanks in advance, cheers.
