Use hardhat to verify smart contracts (goeril testnet)

experience

I wrote a simple Erc721 contract using openzeppelin and successfully deployed it to the goerli test network, but it keeps reporting errors during verification:

Error in plugin @nomiclabs/hardhat-etherscan: Failed to send contract verification request.
Endpoint URL: https://api-goerli.etherscan.io/api
Reason: Connect Timeout Error

At this time, try to solve the problem according to the method on https://github.com/NomicFoundation/hardhat/issues/2348. Connect Timeout ErrorIt is indeed gone, but the following error is reported:

Error in plugin @nomiclabs/hardhat-etherscan: Failed to send contract verification request.
Endpoint URL: https://api-goerli.etherscan.io/api
Reason: read ECONNRESET

I googled for a long time and found nothing, and finally saw this sentence on the issue above ,

so I clicked into the warehouse , followed the README to install the dependencies at first, and found that the installed dependencies were still the same, and then tried to install, @jobinleung/hardhat-etherscanprompting that the package could not be found.
Finally, I had an idea, downloaded the Release from the above warehouse, replaced the original ethscan package , and finally solved this problem. Successful screenshot:

This error is that polling failed to obtain the status, and then I went to ethscan to check the contract, and the verification was successful!

Use this as a record to prevent stepping on the pit again.
