LinkedIn OAuth 2.0 Redirects to Wrong URL

Question

https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id=xxxx&redirect_uri=http%3A%2F%2Flocalhost%3A4200%2Fauth%2Fcallback-linkedin&scope=r_emailaddress

The above URL shows that I have the following URL for redirect:

http://localhost:4200/auth/callback-linkedin

In the app settings I have the same authorized redirect URL. And it also redirects to same page but I get the following error:

errors: Array [ "Something went wrong, please try again." ] response: Object { status: 404, statusText: "Not Found", url: "http://localhost:4200/token", … }

error: "\n\n\n\nError\n\n\n

Cannot
POST /token

\n\n\n"

According to this stackexchange post localhost has been explicitly disallowed by some vendors. Can you try 127.0.0.1 or a locally-resolvable DNS name?
