I am currently new in grpc. I wanted to provide ssl for my grpc server the javav code for starting looks like this:
InputStream publicKey = ServerStarter.class.getResourceAsStream("/my-public-key-cert.pem");
InputStream privateKey = ServerStarter.class.getResourceAsStream("/my-private-key.pem");
SslContext sslContext = GrpcSslContexts.forServer(publicKey, privateKey).build();
Server server = NettyServerBuilder.forPort(5555)
.sslContext(sslContext)
.addService(new RedirectService())
.intercept(new AuthorizationInterceptor())
.build();
server.start();
SSL certificates were generated with openssl. And here how openssl command looks like:
openssl req -x509 -newkey rsa:4096 -keyout ./grpc-server/src/main/resources/my-private-key.pem -out ./grpc-server/src/main/resources/my-public-key-cert.pem -days 365 -nodes -subj "/CN=192.168.88.132" -addext "subjectAltName = DNS.1:192.168.88.132, DNS.2:localhost"
Server runs fine. But I can't connect to server. My clients code looks like this:
InputStream certificate = GalamatClient.class.getResourceAsStream("/my-public-key-cert.pem");
SslContext context = GrpcSslContexts.forClient().trustManager(certificate).build();
ManagedChannel channel = NettyChannelBuilder.forTarget("192.168.88.132:5555")
.sslContext(context)
.build();
GreetingServiceGrpc.GreetingServiceBlockingStub stub = GreetingServiceGrpc.newBlockingStub(channel)
GreetingService.GreetingRequest request = GreetingService.GreetingRequest.newBuilder().setMessage("Hi").build();
GreetingService.GreetingResponse response = stub.greet(request);
channel.shutdownNow();
And when I try to run client next Error occurs:

Error says that I don't provide needed Ip in subject alternative names:
No subject alternative names matching IP address 192.168.88.132 found
but I provided it in command of creation certificate. I will apreciate if you could help with that.
