There's a difference between "Working properly and slow because of the hardware" vs "not working" - please differentiate.
nVidia cards are quite slow for hash cracking, and the Teslas aren't any better - they're actually worse than general gamer cards, because they're clocked slower for reliability and thermals.
They're really not worth it at $2.10/hr - you can build your own system for the cost of one run. If you set them up as spot instances, though, and script the startup/handle the random shutdowns, it gets a lot cheaper.
In general, though, the best answer is "Don't use EC2 for hashcat."
Didn't you just say on twitter that you'd never fire your hashes out into the void?
