Filter events for Polygon Error

Hello, I moved from Eth to Polygon, but the working code now gives me an error:

ValueError: {'code': -32004, 'message': 'filter requests not supported'}

The code (python):

from web3 import Web3

w3 = Web3(Web3.HTTPProvider(UNFURA_HOST))
...
event_filter = w3.eth.filter({'fromBlock':from_block, 'address':contract_address})
...

Am I doing it wrong? I want to get events from the contract
