Early morning the free service most of crypto faucets use "nastyhosts" stopped responding.
Since nastyhosts is down all the Faucet In A BoxUltimate crypto faucets fail during a claim with a "Couldn't connect to NastyHost, refusing to payout!"
If you want your faucet(s) to work properly you have to disable "nastyhosts".
Since it is dangerous to run unprotected I've created a temporary WaterfllManager API Key for free use: demoapi
I'll disable the key once "nastyhosts" is back up.
12.04.2018 UPDATE: Nastyhosts is back up. The free WaterfllManager API Key will be deleted soon.
