Etherscan request times out when requesting constructor args

I followed the instructions but failed.

Running truffle-plugin-verify v0.4.0
Verifying Token
Reading artifact file at E:\MyProject\BlockChain\truffle-contracts\abis/Token.json
Retrieving constructor parameters from https://api-ropsten.etherscan.io/api?apiKey=my_api_key&module=account&action=txlist&address=0x4C9D6ed005bfB301726cA23adE690890B853fB60&page=1&sort=asc&offset=1
Failed to connect to Etherscan API at url https://api-ropsten.etherscan.io/api
Failed to verify 1 contract(s): Token

It seems the network problem. But It migrated successfully. when I try to connect to the verify url, it returns right:

PS E:\MyProject\BlockChain\truffle-contracts> curl https://api-ropsten.etherscan.io/api

Hey @JoyCood, could you give it a quick check to see if it’s currently still persisting for you? Likewise also, @white-black-hong - Is this still happening? Thanks.

unfortunaly, it is not work yet, the output after command run:

$ truffle run verify Adoption --network rinkeby --debug

You can run the command export https_proxy="http://127.0.0.1:1087" to set the endPoint proxy, remember to replace the port with your network proxy setting.It works for me.

I miss the same problem. The reason for my problem is: the ip obtained by DNS resolution of the domain name cannot be connected. I check api-rinkeby.etherscan.io get useable IP, add this IP mapping api-rinkeby.etherscan.io to my local hosts file. Then I solve this problem.

That’s get domain name mapping IP network. https://url5.co/?t=1636355893
