尝试访问同一n上的grpc服务器时，grpc客户端dns解析失败

Question

我试图从Python客户机调用运行在.Net核心项目上的GRPC服务器。在

当在localhost:5001上运行时，它工作得很好，但是在同一个网络（如192.168.1.230:5001）中运行机器的实际IP时，它不起作用，我得到一个错误DNS resolution failed。在

我已经下载了SSL证书，目前正在从客户端以文件的形式读取它。它在运行localhost时起作用，所以我不认为这是问题所在。在

有没有更好的方法来进行这种测试，让客户机运行在与服务器相同的网络上的不同设备上？在开发过程中把GRPC服务器托管在外面并不是最好的解决方案。在

Python代码：

import grpc
import datamessage_pb2 as datamessage
import datamessage_pb2_grpc as datamessageService


def main():
    print("Calling grpc server")
    with open("localhost.cer", "rb") as file:
        cert = file.read()
    credentials = grpc.ssl_channel_credentials(cert)
    channel = grpc.secure_channel("https://192.168.1.230:5001", credentials)
    # channel = grpc.secure_channel("localhost:5001", credentials)
    stub = datamessageService.StationDataHandlerStub(channel)
    request = datamessage.StationDataModel(
        temperature=22.3, humidity=13.3, soilMoisture=35.0)

    result = stub.RegisterNewStationData(request)
    print(result)


main()

Program.cs中的服务器设置：
