Server side rendering issue for some pages only

Question

The routing part didn't work on SSR by typing directly in the browser the path or click on a tag to open a new link. By example: The first entry route is: user, inside user click to change the route to products works normally. From products go to products/:id works perfectly. But if I type in directly in the address bar the url by example: localhost:4200/products/1 it will never find out where is the route and turn out 504 error Gateway time out.
