Problem: JSON-RPC depends on setting in client.toml

[samuel-tay]

Describe the bug
If all settings are default, there is no issue. However, if laddr = "tcp://0.0.0.0:26657" is modified in config.toml and node = "tcp://localhost:26657" not updated in client.toml, then json-rpc will have issues.

I haven't fully tested, but I used web3.py and tried to request w3.eth.get_block(block_identifier='latest') and web3.exceptions.BlockNotFound: Block with id: 'latest' not found will be thrown. This was resolved when client.toml was configured to matched laddr in config.toml

To Reproduce
Web3 code can be provided on request.

Expected behavior
I would expect the json-rpc on the node to read the node config from config.toml instead of client.toml

Additional context
Problem might be from Tharsis

[yihuang]

I don't reproduce the issue on main branch, what I do:

• init devnet
• change client.toml's node to different port
• start devnet
• try web3 code:

>>> w3 = web3.Web3(provider=web3.HTTPProvider('http://localhost:26651'))
>>> w3.eth.get_block('latest')

I just tried a few more times and it is exactly as I described. I'm using 0.6.5

[yihuang]

did you disable the rest-api and grpc server? in that case it doesn't use the "local" client. try enable the grpc or API server.

EDIT: I just reproduced the same issue by disable both grpc and API servers.

[yihuang]

will be fixed by evmos/ethermint#988.

[samuel-tay]

Thanks @yihuang for fixing this so quickly! Your right, I did disable both api and grpc as you mentioned.
