Cryptographic Challenge from Server

[elprl]

I noticed you manually created the challenge using a random set of numbers. This is supposed to come from a server right?
What's the trade-off to it being manually created here?

Any idea how to setup this up on something like Firebase or Lambda cloud functions?

Yes, it should definitely come from the server. I was not able to continue with the server so far, so I will keep it open for now.
