Try to get the newest client you can. The server is running the development version of MT 0.4.14 released 2016_09_14. sfan5 and krock seem to be keeping up more current builds for Windows (32 bit and 64 bit - both work). If you are using Linux, the repository versions may be too old (but worth a try). If so, you'll either have to wait for an updated PPA or compile yourself. If you are running Ubuntu or Debian, compiling Minetest is easy, just follow the instructions in Minetest's README.txt file.
