If your trying to connect to a 0.8.1 and below server, you won't be able to join. If you can't join the server and it's 0.9.x, it's either offline or your internet.
There are servers that use the PocketMine Beta version for 0.9, but its Beta version. We are waiting out for the stable one to come out. A few amount of servers will work for 0.9.0 + at the moment, because most of the server owners prefer to have a server with stable version, not beta one. The Beta version is like a test version to run a server. Its not STABLE. It is causing lag and glitches yet to many things....
The 0.9.0 + servers you are seeing at the moment are using the PocketMine Beta version. So my hint for you is to stay to singleplayer for now and stay updated here on the forums. I hope I helped. "
