verification of contract with hardhat-etherscan broken again

[JEflyer]

When verifying my contract 5 days ago it worked, then it broke & started working again & now it has broke again.

Is there a ETA for this to be stable & working again?

I've updated to the latest version of hardhat-etherscan & tried previous versions with no working result.

The error I'm receiving is the same as I got when it last broke.

NomicLabsHardhatPluginError: The contract verification failed.
Reason: Fail - Unable to verify

I'm having the same issue.

Good to know I'm not the only one :')

Same issues here 😔

@JEflyer in which network are you trying to verify the contract?

[fvictorio]

I was able to verify a contract on Rinkeby. We'll need a minimal reproducible example to be able to investigate this. Please don't add "same issue" comments unless you can provide one.

Same issues here! I was able to verify a contract on Rinkeby and Ropsten.

@italosantana did you read what I wrote before commenting?

Hey @fvictorio

Just created a new repo to test from scratch. Both rinkeby and ropsten contract verification seems to be working at the moment.

I had issues earlier for about 12 hours and had stopped trying until now. If I remember correctly I was getting 403 with some html page throw as the error in the console.

If I encounter it again I'll post a screenshot and a reproduction case. Maybe it had to do with Etherscan api's. Perhaps error logging could be improved if Etherscan was the cause to make it clear that it has nothing to do with Hardhat but the underlying api is having issues.

Hi, now I can verify my code.

Yesterday, I failed verifying code that I could verify before, so I imagine that was something internal.
Anyway, it works now so I think we can close this issue
