401 Client Error: Unauthorized for url

Hi, I am getting this error when trying to run my contract over brownie:

HTTPError: 401 Client Error: Unauthorized for url: https://rinkeby.infura.io/v3/{my API key}

This is the command I am running :

brownie run scripts/deploy.py --network rinkeby

I set my .env file like this:

export PRIVATE_KEY={private key}
export WEB3_INFURA_PROJECT_ID={my API key}

I tried to:
-Delete my account and create a new one
-Delete and create new projects over and over
-Change to another testnet like Ropsten

My rinkeby wallet has exactly 0.2357RinkebyETH.

Please, if someone could help me I will apreciate it.

Hi there Pablo and welcome to our community!

On a first look, it might be that your .env file is set up incorrectly. Here is how mine is configured (the project ID and Private Key are dummy data that do not work, these should never be shared with anyone else):

Then, to access the private key in my python code I use ‘os’, like this:

import os

private_key = os.getenv('SIGNER_PRIVATE_KEY')
