gRpc 客户端：Python:3.8 grpcio:1.38.1

gRpc 服务器：Dotnet core 5.0 LoadBalancer AKS：1.19.7

当我的 python 客户端调用方法时，出现以下错误。非常感谢任何解决问题的帮助。

Python 代码片段

with open('chain.pem', 'rb') as f:
        trusted_certs = f.read()

credentials = channel = grpc.ssl_channel_credentials(root certificates=trusted_certs)

# 10.200.3.24 is the K8S service IP with 3 replicas
channel = grpc.secure_channel('10.200.3.24:443', credentails, options=(('grpc.enable_http_proxy', 0),))

stub = query_pb2_grpc.QueryStub(channel)

empty = google_dot_protobuf_dot_empty__pb2.Empty()
data = stub.TestMethod(empty)

错误
