Expected Behavior

I expected to receive the cosmos hub's wallet balance:

`tests_address = 'cosmos1rtpgucu3pjrelph4flzg6hr5ntt6yw56l0qvx5'

generated_wallet = LocalWallet.generate(prefix='cosmos')

cfg = NetworkConfig(
    chain_id="Cosmos-Hub",
    url="grpc+https://grpc-cosmoshub.blockapsis.com:429",
    fee_minimum_gas_price=1,
    fee_denomination="uatom",
    staking_denomination="uatom",
)
cl = LedgerClient(cfg)

res = cl.query_account(address=Address(tests_address))`

Current Behavior

Getting the error:

grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with: status = StatusCode.UNAVAILABLE details = "Received http2 header with status: 502" debug_error_string = "{"created":"@1661773704.783000000","description":"Error received from peer ipv4:52.9.100.62:429","file":"src/core/lib/surface/call.cc","file_line":967,"grpc_message":"Received http2 header with status: 502","grpc_status":14}"
