NamelessMC

I dont know if this is right.
currently the plugin spits out a error every few minutes.

Caused by: java.net.UnknownHostException: bitcubes.eu

the weird thing is that my server is fully reachable every second i even did a day scan measuring every 30 seconds if my server is reachable and online and yes no outages and a responcetime within 22 ms.

can someone explane why this happens. beside that i have installed NamelessMC in a subdir (bitcubes.eu/mc) so i have no clue why its just pointing to bitcubes.eu instead of the subdir
