I’ve deployed a dev project using openvidu with selfsigned certificate on AWS stack. I am using angular tutorial for development mode. I have replace the server url with my server url ![image](https://global.discourse-cdn.com/free1/uploads/openvidu/original/2X/7/745b95ecd665454fdde86ae27a35119cec966f5f.png) Below is the code: import { HttpClient, HttpHeaders } from ‘@angular/common/http’; import { Component, HostListener, OnDestroy } from ‘@angular/core’; import { OpenVidu, Publisher, Session, StreamEvent, StreamManager, Subscriber } from ‘openvidu-browser’; import { throwError as observableThrowError } from ‘rxjs’; import { catchError } from ‘rxjs/operators’; @Component({ selector: ‘app-root’, templateUrl: ‘./app.component.html’, styleUrls: [’./app.component.css’] }) export class AppComponent implements OnDestroy { OPENVIDU\_SERVER\_URL = ‘[https://ec2-15-206-138-138.ap-south-1.compute.amazonaws.com](https://ec2-15-206-138-138.ap-south-1.compute.amazonaws.com)’; OPENVIDU\_SERVER\_SECRET = ‘\*\*\*\*\*\*\*\*’; // OpenVidu objects OV: OpenVidu; session: Session; publisher: StreamManager; // Local subscribers: StreamManager[] = []; // Remotes // Join form mySessionId: string; myUserName: string; // Main video of the page, will be ‘publisher’ or one of the ‘subscribers’, // updated by click event in UserVideoComponent children mainStreamManager: StreamManager; constructor(private httpClient: HttpClient) { this.generateParticipantInfo(); } @HostListener(‘window:beforeunload’) beforeunloadHandler() { // On window closed leave session this.leaveSession(); } ngOnDestroy() { // On component destroyed leave session this.leaveSession(); } joinSession() { ``` // --- 1) Get an OpenVidu object --- this.OV = new OpenVidu(); // --- 2) Init a session --- this.session = this.OV.initSession(); // --- 3) Specify the actions when events take place in the session --- // On every new Stream received... this.session.on('streamCreated', (event: StreamEvent) => { // Subscribe to the Stream to receive it.
