About MapleStory Help
Troubleshooting for MapleStory server owners across v83, v62, v117.2, v117, v142.2, v75, v111, v160 and v97 - connection errors, database problems, client crashes and configuration mistakes.
Most problems posted here come down to a handful of causes: the client pointing at the wrong address, a database the server cannot reach, a missing runtime library, or a port that was never opened. Search before posting - the same MapleStory errors come up often and usually already have an answer.
Most MapleStory server files target the v83 client, typically Java against MySQL, though v55, v62, v75, v97, v111, v117, v117.2, v142, v144.3 and v145 all appear, plus a Delphi server covering v83, v90 and v97. Named sources, repacks and emulators include OdinMS, MoopleDEV, HeavenMS, TitanMS and its fork Vana, XiuzSource, Lithium, ExiledMS, JudoMS, ShineMS, NakedStory83, Acernis and OdinSEA, with Cype CMS and MapleBitCMS for the website, HaRepacker, and WZ and XML editing. Guides on Windows use WampServer, NetBeans, MySQL Query Browser and the JDK; missing JCE Unlimited Strength files give the login stick error, and localhost needs hex editing or a redirector such as IPredirect to avoid Hamachi.

Common questions
- Why does my MapleStory v83 server disconnect immediately after login?
- Disconnecting the instant a character loads, with a connection error, is the signature of the JCE Unlimited Strength policy files being absent from the JDK. The server accepts the connection and then fails on the cipher, so the client is dropped. Installing the policy files for the exact JDK the server runs under clears it; reinstalling Java on its own does not, because the files are a separate download.
- How do I unpack MapleStory.exe to work on a private server?
- The executable is packed, so the packer has to be identified before anything can be read. ProtectionID reports both which packer was used - Themida, ASProtect and Yoda all appear across versions - and which version of it, and the unpacking method follows from that pair. Different client versions use different packers, so the answer for one build does not carry to another.
- Which MapleStory source should a new private server start from?
- Nearly everything in circulation descends from one line, and the client version decides the branch. HeavenMS is the usual v83 starting point, with Cosmic continuing that line, while v62 work sits on its own older lineage from OdinMS and MoopleDEV. ExiledMS covers v117. Picking the source first and the client version second is the wrong order - the client build constrains which sources will run at all.
