Hi, welcome! 
I am not sure for this, maybe there is something wrong with the faucet. And I think if one network does not work, maybe you can use another one or the local environment to have a test.
Just send you some Rinkeby Ether.
And for the next time, please search at the forum at first, and then ask questions, thanks!
