Invalid JSON RPC response: " "

Following readme. Able to connect to the test network etc and then suddenly can't deploy the contracts themselves.

I've triple checked that all of my exports are correctly set and that my wallet on the rinkeby network has funds.

± |master ✓| → DEPLOY_CREATURES_SALE=1 yarn truffle deploy --network rinkeby
yarn run v1.22.10
$ /Users/johnlshankman/Documents/workspace/opensea-creatures/node_modules/.bin/truffle deploy --network rinkeby

Exactly same error

I'm not sure about it, but my mistake was to use a wrong node versione (I did yarn install --ignore-engines in order to ignore the versione required).
I started from scratch with the correct node version (used nvm to install version 12.18.4) and the mint worked flawlessly

I also have a similar problem can someone please help me?

@johnnyshankman
it can be related to the internet connection

also it is mentioned in docs in troubleshooting section that
It doesn't deploy anything!
This is often due to the truffle-hdwallet provider not being able to connect. Go to your Alchemy Dashboard (or infura.io) and create a new project. Use your "project ID" as your new ALCHEMY_KEY and make sure you export that command-line variable above.
