Probable cause is that the specified All That Node provider for testnet has been shut down: [Important] dYdX Testnet Public Node endpoints will no longer be supported as of November 29th, 2023 at 15:00 UTC.
Setting up a node on testnet, and modifying the network configuration could be a possible work around. Note: running a node without TLS may require to let the library know, see this line in python.

thank you for your response, I use the mainnet config, it also shows

there is a bug in v4-client-py/v4_client_py/clients/modules/post.py line 46 to get testnet network config. Below change can fix the problem

change source code as following (post.py)
#network = NetworkConfig.fetch_dydx_testnet() #bug to get testnet network config
network= NetworkConfig( #Mainnet setup
chain_id=self.config.chain_id,
url=self.config.grpc_endpoint,
fee_minimum_gas_price=0,
fee_denomination="adydx",
staking_denomination="adydx",
faucet_url=None, )
