Error: Invalid JSON RPC response

[murilobast]

When I try to run tokenpool on my vps I get this error:

UnhandledPromiseRejectionWarning: Error: Invalid JSON RPC response: ""

It looks like it isn't getting a valid response from mainnet on web3

Ok, just got why I am getting this error.
I need an RPC server to connect but the question now is:
Can I use a public RPC like "https://api.myetherapi.com/eth" or do I need to setup a private one?

I got the same errors.
Can anyone help me?
Here is message.
