Error Message accoring whitelist add

[cndrbrbr]

Hi there,
I tried different Versions (1.8 and 1.7.10) of the canary mod server.
I need user management.
Should this work?

Is Java behind some sort of firewall? If so that's probably why.

A work around is to input the UUID instead, you can use Nodecraft's MCUUID service to get that - http://mcuuid.net/

Another workaround is to disable the whitelist, have the player connect, then add then to the whitelist, then enable it again.

wl disable
player x joins
wl add x
wl enable
