Kubernetes Cluster Designs and Specifications for Ethereum-based Networks

Ethercluster

Ethercluster is an Ethereum-based node infrastructure design and specification that allows anyone to build easily scalable dapp infra without relying on third-party endpoints. It uses the latest cutting-edge infra-as-code technology found in dev-ops, such as Terraform, Kubernetes, and Docker.

ethercluster's Issues

CORS Error on Ethercluster

Describe the bug
CORS bug error when attempting to RPC call Ethercluster.

I am hitting the following error when making RPC calls against  https://www.ethercluster.com/etc

"Access to XMLHttpRequest at 'https://www.ethercluster.com/etc' from origin 'https://buidl.secondstate.io' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

SSL Error when using Python web3

Describe the bug
Getting a SSLError when accessing ethercluster RPC endpoint via Python web3

To Reproduce

from web3 import Web3, HTTPProvider
web3 = Web3(HTTPProvider("https://www.ethercluster.com/etc"))
latestBlockNumber = web3.eth.getBlock('latest').number

Returns the following

Traceback (most recent call last):

Kotti fails to return balance

The attached html file is failing to log the balance. The account is listed on the Kotti Faucet, and the code works with other blockchains (I've no other way to debug Kotti account).

The error is:

Access to fetch at 'https://www.ethercluster.com/kotti' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Why https://www.ethercluster.com/kotti is not wokring?

I am trying to setup a kotti network in my metamask browser wallet. The rpc url for kotti is not working any more and the documentation in ether cluster still suggests to use the same rpc url https://www.ethercluster.com/kotti. Why is that?
