Indexer Agent and Service connection issue to ETH node over http

[86b]

When declaring --ethereum, INDEXER_SERVICE_ETHEREUM, or INDEXER_AGENT_ETHEREUM with an http endpoint, a NETWORK_ERROR occurs. Here are the errors for the indexer agent and service:

When specifying an endpoint with https, everything works as expected.

+1 on this. Tested with turbogeth, geth and about to test with openeth aswell but expecting same results.

[fordN]

I think the http vs. https is a red herring; the issue appears to be related to: ethers-io/ethers.js#866

@cryptovestor21 a few questions:

• Were you able to test with an openethereum node?
• Were the nodes you tried connecting to all on the same network,Rinkeby?
• Did you have the net RPC API enabled on the Geth/Turbogeth node?

Confirmed fix is working via Docker on images:
