i used 8545 port directly, not meta-mask injected web3 apis.
i'll try with metamask with injected web3

Hi @leejw51crypto , do you have any ideas that I was trying to connect http://localhost:8545 Web3 Provider by Remix http://remix.ethereum.org/, but got error: Not possible to connect to the Web3 provider. Make sure the provider is running, a connection is open (via IPC or RPC) or that the provider plugin is properly configured.

I have enabled the cors of the api config in app.toml.
