Rinkeby Etherscan Verification pending then fails

Question

I've seen similar questions but none with a working answer unfortunately. I'm following along with the Brownie FundMe tutorial from freecodecamp youtube and my etherscan verification won't work.

Here is the output from 'brownie run scripts/deploy.py --network rinkeby':

Brownie v1.18.1 - Python development framework for Ethereum

BrownieFundMeProject is the active project.

Running 'scripts\deploy.py::main'...

Contract deployed to 0xf50aA945B5fd2e6336631B71a5929A09a21a741E

And here is my script (the wait statement was suggested in another thread but didn't work):

from brownie import FundMe
from .helpful_scripts import get_account

def deploy_fund_me():
    account = get_account()
    fund_me = FundMe.deploy({"from": account}, publish_source=True)
    # fund_me.wait(1)
    print(f"Contract deployed to {fund_me.address}")

def main():
    deploy_fund_me()

Finally, the config file:

dependencies:
  # - <organization/repo>@<version>
  # https://github.com/smartcontractkit/chainlink-brownie-contracts
  - smartcontractkit/chainlink-brownie-contracts@0.4.0
compiler:
  solc:
    remappings:
      - '@chainlink=smartcontractkit/chainlink-brownie-contracts@0.4.0'
dotenv: .env
wallets:
  from_key: ${PRIVATE_KEY}

What am I doing wrong that's causing this to fail? The contract clearly deploys but the etherscan verification is failing.

Any advice would be greatly appreciated.

I went through his course also, so I see where you're stuck, I would check to make sure the API key was imported correctly from Etherscan as this is a verification issue. Take a look at your .env file, let me know if you're still dealing with an issue!
