Metamask is not connecting my blockchain network

Question

I'm building a todoList Web-App using blockchain. I'm stuck when I tried to connect the blockchain server to metamask. When I try to add new network as mentioned in my Ganache(HTTP://127.0.0.1:7545) then I miss chainID and When I fill the chainID with Genache network Id it shows the given error.

When I try to connect to localhost8545 then it returns this error:

trufle-config.js

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*" // Match any network id
    }
  },
  solc: {
    optimizer: {
      enabled: true,
      runs: 200
    }
  }
}

How can I connect my blockchain network with my localhost?

Answer 1

remove default localhost account (i.e. Localhost 8545 ) first and then add the new network with details and chain ID as 1337

Answer 2

• Open metamask extenuation settings
• find there network
• click on it
• find localhost 8545
• remove it
• try create new with 1337
