Title and Meta tags not rendering in angular SSR in server

I have developed a website using Angular 6 in the frontend. By default Angular is not SEO friendly, so in order to do that, I implemented it in the way of Angular-Universal or Angular SSR (Server Side Rendering). I updated the code and comparing the page sources from before and now, I can see my application inside the tags <app-root> and </app-root>, before only "loading..." would come.

I am using the MetaService and TitleService from @angular/platform-browser to update the desired <meta> tags for Facebook and Twitter and the <title> tag respectively.

The problem is when I run the node server in my local system, view-source shows me the rendered meta tags, but when I run the same code in node server on AWS VM, I don't get the rendered meta tags, but other application code is available.
