gRPC无法创建从客户端（Python）到服务器（Go）的连接

Question

我有此Python代码，该代码应使用证书并通过服务器的IP地址（没有可用的FQDN）连接到服务器，但是每次尝试都会出现错误：

ssl_transport_security.cc:222]                 LOOP - TLS client process_change_ciph  - !!!!!!
ssl_transport_security.cc:222]                 LOOP - TLS client read_server_finishe  - !!!!!!
ssl_transport_security.cc:222]                 LOOP - TLS client finish_client_hands  - !!!!!!
ssl_transport_security.cc:222]                 LOOP -                TLS client done  - !!!!!!
ssl_transport_security.cc:222]       HANDSHAKE DONE -                TLS client done  - !!!!!!
security_handshaker.cc:184] Security handshake failed: {"created":"@1582052112.923538253","description":"Peer name 172.18.0.14 is not in peer certificate","file":"src/core/lib/security/security_connector/ssl/ssl_security_connector.cc","file_line":55}
subchannel.cc:1003]         Connect failed: {"created":"@1582052112.923538253","description":"Peer name 172.18.0.14 is not in peer certificate","file":"src/core/lib/security/security_connector/ssl/ssl_security_connector.cc","file_line":55}

subchannel.cc:967]          Failed to connect to channel, retrying

据我了解，这可能是由于我连接到IP地址而不是FQDN，但这是服务器，并且我只能访问IP地址。知道如何克服这个问题吗？

使用的Python代码：

def get_secure_channel(host, port):
    if os.environ.get('https_proxy'):
        del os.environ['https_proxy']
    if os.environ.get('http_proxy'):
        del os.environ['http_proxy']

    with open(os.path.join(settings.DJANGO_ROOT, '../grpc_proto/cert/server.crt'), 'rb') as f:
        cert = f.read()

    credentials = grpc.ssl_channel_credentials(root_certificates=cert)
    return grpc.secure_channel('{}:{}'.format(host, port), credentials)

def reset_client(channel, ip_address):
    stub = dnsadblock_pb2_grpc.DnsadblockServiceStub(channel)
    return stub.ResetClient(dnsadblock_pb2.ResetClientRequest(ipAddress=ip_address))

channel = get_secure_channel(c.server.hostname, settings.GRPC_PORT)
rpc.reset_client(channel, c.ip_address)
