import asyncio

from pytoniq import LiteClient


async def main():
    client = LiteClient.from_mainnet_config(  # choose mainnet, testnet or custom config dict
        ls_i=0,  # index of liteserver from config
        trust_level=0,  # trust level to liteserver
        timeout=15  # timeout not includes key blocks synchronization as it works in pytonlib
    )

    await client.connect()


if __name__ == '__main__':
    asyncio.run(main())

With some probability I get:
