GRPC Golang服务器和NodeJS客户端。 TLS连接失败

Everything works fine when I don't use TLS. But when I do, it does not connect. More details:

I have configured the Golang GRPC server exactly like how this blog says https://bbengfort.github.io/programmer/2017/03/03/secure-grpc.html in Mutual TLS with Certificate Authority section. The server is up and running just fine.

Now I have a client written in NodeJS, trying to send some data through grpc. I have configured the NodeJS like below:

var PROTO_PATH = __dirname + '/protos/log.proto';
var grpc = require('grpc');
var protoLoader = require('@grpc/proto-loader');
var packageDefinition = protoLoader.loadSync(
    PROTO_PATH,
    {keepCase: true,
     longs: String,
     enums: String,
     defaults: true,
     oneofs: true
    });
    
var ssl_creds = grpc.credentials.createSsl(fs.readFileSync('ssl/ca.crt'), fs.readFileSync('ssl/client.key'), fs.readFileSync('ssl/client.crt'));

var log_proto = grpc.loadPackageDefinition(packageDefinition).log;
var client = new log_proto.LogData('<IP>:<PORT>',ssl_creds); 

I created the certificates like how it is mentioned here: https://github.com/grpc/grpc/issues/6757. Ofcourse, i did see this comment: https://github.com/grpc/grpc/issues/6757#issuecomment-264617793.

I am still seeing the error when I run NodeJS client:

{ Error: 14 UNAVAILABLE: Connect Failed
at Object.exports.createStatusError (/app/node_modules/grpc/src/common.js:91:15)

code: 14,
metadata: Metadata { _internal_repr: {} },
details: 'Connect Failed' }

Certificate details: SSLv3 TLSv1.2

EDIT:

I added env variable GRPC_VERBOSITY as DEBUG and found the following: Peer name <IP> is not in peer certificate

</div>

So the issue was that the certificate couldn't hold IP address as the hostname. It should have a name and not an IP - fixed it by providing a name and overriding the target name.

const options = {
  'grpc.ssl_target_name_override' : 'simple-host',
  'grpc.default_authority': 'simple-host'
};
var client = new log_proto.LogData('<IP>:<PORT>',ssl_creds,options);
