Splunk JavaScript API- Why do I get an error when I try to use SDK to login remotely?

[BryanK]

const splunkjs = require('splunk-sdk');

const service = new splunkjs.Service({
    host: "xxxxxx",
    port: xxxx,
    username: "administrator",
    password: "xxxxxx",
    scheme: "https",
    version: "default"
}
);

const init = new splunkjs.Service
service.login(function(err, success) {
    if (err) {
        throw err;
    } else {
        console.log('Logged in successfully');
    }
}
);

Hey, 
I was trying to use the SDK to login remotely however the server keeps returning an error message as shown below. I even tried using postman on the local splunk server but it gives the same error as well. 

{
  response: { headers: {}, statusCode: 600 },
  status: 600,
  data: undefined,
  error: Error: write EPROTO 22680:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3_record.c:332:
  
      at WriteWrap.onWriteComplete [as oncomplete] (node:internal/stream_base_commons:94:16) {
    errno: -4046,
    code: 'EPROTO',
    syscall: 'write'
  }
}

However on the local server I am able to login just fine with the code shown below however I really don't want to do development on the splunk server directly as its quite a pain

const service = new splunkjs.Service({
    username: "xxx",
    password: "xxx"
}
);
