    *firebaser here* This error occurs internally in the Firebase client, because the responses from the server don't match the expected headers in the handshake. My best guess is that there is some system between this client and the Firebase servers that mangles the traffic, resulting in the Firebase client being unable to parse it. – Frank van Puffelen Apr 29 '17 at 14:01

Error is caused by casting String.toLowerCase on a null object. Post your java.class for more information, or just check where you cast objects to String.toLowerCase and see if they possibly have a null reference. Fixing that should do the job.
