web3.py error - 401 Client Error: Unauthorized for url

I am trying to build smart contract on ethereum. I have next error in my code - "requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url:"

I am using next stack:

• Python 3.9 / web3.py
• Node.js
• Truffle
• Infuria
• Ethereum Ropsten Test Network

Any ideas?)
