How can I make Handshake between client and https server

Question

I'm working on project that requires secure connection between Client (which is Android Device) and Server which is (Nestjs app)
and for generating my certificate I'm using openSSl this is the link I followed
Link : Tuto openSSL
I configured main.ts as shown below :

import { NestFactory } from '@nestjs/core';
import { NestExpressApplication } from '@nestjs/platform-express';
import { AppModule } from './app.module';
import * as fs from 'fs';

const httpsOptions = {
  key: fs.readFileSync('certssl/CA/localhost/localhost.decrypted.key'),
  cert: fs.readFileSync('certssl/CA/localhost/localhost.crt'),
};
async function bootstrap() {
  const app = await NestFactory.create<NestExpressApplication>(AppModule, {
    httpsOptions,
  });

  await app.listen(443);
}
bootstrap();

and this is my gateway.ts file

import { Logger } from '@nestjs/common';
import {
  MessageBody,
  OnGatewayConnection,
  OnGatewayDisconnect,
  OnGatewayInit,
  SubscribeMessage,
  WebSocketGateway,
  WebSocketServer,
  WsResponse,
} from '@nestjs/websockets';
import { Server, Socket } from 'socket.io';

@WebSocketGateway({
  cors: {
    origin: '*',

    transports: ['polling', 'websocket'],
  },
})
export class AppGateway implements OnGatewayInit, OnGatewayDisconnect {
  handleDisconnect(client: any) {
    this.logger.log(`Disconnected ${client.id}`);
  }
  @WebSocketServer() server: Server;
  private logger: Logger = new Logger('GatewayApp');

  afterInit(server: Server) {
    this.logger.log('Initiate Gateway');
  }
  handleConnection(client: Socket) {
    client.emit('connection', 'Success from server');
    this.logger.log(`connected ${client.id}`);
  }

  @SubscribeMessage('events')
  handleEvent(@MessageBody() data: string): string {
    this.logger.log(data);
    return 'data recieved';
  }
}

Finally I get This result
Image Result Everything works fine :)
In case you want information of my certificate :
