Load your RPG-X, RPG-X2
Open your Console
and enter the following command
/sv_master3 "efmaster.kickchat.com"
once that is done, go to te normal screen to scan for servers.
Change from Internet 1 to Internet 3
This has worked on mine and several other peoples systems.
If this still doesn't work, you can connect manually by clicking on "specify server," and filling in server.last-outpost.net (RPG-X) or server.last-outpost.net:27961 (RPGXEF)
I don't see our server on that list o.0
Our server should be appearing on that list now!
Stickied.
On a sidenote, that Internet 3 server "should" already be the default if you have RPG-X EF installed, atleast this was the case for me.
I have heard from other people this is not the case for vanilla or ioEF, so you need to do the console command Jantrix said.
FYI, the regular master server master.stef1.ravensoft.come does appear to be working again. You can also try thilo.kickchat.com.
