FlyFF Help

Troubleshooting for Flyff server owners across v19, v15 and v18 - 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 Flyff errors come up often and usually already have an answer.

Flyff private server setup starts from v15 and v14 official repacks, with v11 to v13, v16, v17, v18, v19 and a v21.2 official source circulating from 2008 to 2026. Named sets include Blessed Infinitum, Dits V16.8, Clean Source, ImMorTaLFlyff V19, Virtuos v19 and the VS22-built Ketchup, Florist and Sakura Project files. The C++ source compiles under Visual Studio 2003, 2017 and 2022 against MSSQL on Windows, splitting login, world and cache servers, connection.ini on port 15400. Neuz needs its salt changed, its IP set and GameGuard removed. ATools, ResEditor, NPC and quest editors cover .o3d, .dds and propitem.txt. Glaphan and Rune are v6 emulators, Rune on pthread and MySQL.

Common questions

Why will my Flyff client not connect to the server?

Nearly always the address the client is pointed at. On many builds the server address sits inside a packed client file rather than a plain text config, so it has to be edited there. Check as well that the server is listening and the port is actually open.

Why will my Flyff server not start?

Usually a database it cannot log in to, a missing runtime, or a port already in use by something else. The server console or log normally names the cause on the first failure, and the processes often have to be started in a particular order.

How do I get a useful answer about Flyff here?

Post the Flyff build you are running, the file set you used, the exact error text and what you have already tried. Threads with that detail get answered; vague ones usually do not.
