[Solved] Remote URL test failed: Could not read from remote repository.

Reason:

I set a password when I generated the key, which caused this problem

Soution:

1. Regenerate the key through the command

ssh-keygen -t rsa -C "[email protected]"

Enter three times in a row, do not set a password (I just set a password here and caused the problem)

2. Go to C:\Users\username\.ssh and copy the content of id_rsa.pub, and then add it to gitlab (title will be automatically generated)

[Solved] hardhat Failed to Verificate Error: Failed to send contract verification request

My workaround

Just like you, my first suspicion was on the GFW and I set up my hosts file like you did.
ping success with and without VPN, which means there is NO connection issue between our computers and the domain.

Since there was almost no waiting time when my console emit the error messages,
it really didn’t feel like a timeout error.

secure TLS connection in the error message got my attention.
Is there a way we could modify the endpoint URL to http protocol?

Luckily yes:
hardhat-etherscan | Ethereum development environment for professionals by Nomic Foundation

I tried the following:

etherscan: {
  apiKey: {
    rinkeby: ""
  },
  customChains: [
    {
      network: "rinkeby",
      chainId: 4,
      urls: {
        apiURL: "http://api-rinkeby.etherscan.io/api",  // https => http
        browserURL: "https://rinkeby.etherscan.io"
      }
    }
  ]
}

Then everything works with and without VPN.
