Can't connect to http://localhost:54321

Hello,

i want to run the lilikoi example code with the mock data provided by the lilikoi R package, however, I am stuck at the lilikoi.machine_learning() command due to a connection error with H2O.

I downloaded the H2O file and unzipped it in the R Terminal, but now I cannot connect to http://localhost:54321 as indicated by your website (https://h2o-release.s3.amazonaws.com/h2o/rel-zygmund/4/index.html).

Below is the error message I get, copied from my R console:

H2O is not running yet, starting it now...

Note:  In case of errors look at the following log files:
    C:\Users\LUISEB~1\AppData\Local\Temp\Rtmp6HnISl\file2abc38ab39e6/h2o_Luise_Bellach_started_from_r.out
    C:\Users\LUISEB~1\AppData\Local\Temp\Rtmp6HnISl\file2abc5e38704f/h2o_Luise_Bellach_started_from_r.err

this loops multiple times and the % bar doesn't move.
