Page is not open with a domain url set in React default page

Question

I have a React FE app which I run using the default localhost:3000 url address.

When I change the default url to a custom domain and upload it on nginx I get into Spring authorization server only this: GET http://111.111.111.111:30121/.well-known/openid-configuration

Payload:

{
  "issuer": "http://111.111.111.111:30121",
  "authorization_endpoint": "http://111.111.111.111:30121/oauth2/authorize",

  ],

  ],
  "scopes_supported": [
    "openid"
  ]
}

The page is blank when I open it. I added this Spring Authorization Server client configuration:

    @Bean
    @Primary
    public InMemoryRegisteredClientRepository usersRegisteredClientRepository() {
        RegisteredClient tokenExchangeClient1 = RegisteredClient.withId(UUID.randomUUID()
                        .toString())
                .clientId(clientId)
                .clientSecret(passwordEncoder().encode(clientSecret))
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN)
                .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
                .scope(OPENID)
                .scope(PROFILE)
                .scope(EMAIL)
                .scope("offline_access")
                .redirectUri("http://localhost:3000/dashboard")
                .redirectUri("http://localhost:3000/sign-in")
                .redirectUri("http://mypublicdomain.com/dashboard")
                .redirectUri("http://mypublicdomain.com/sign-in")
                .clientSettings(userClientSettings())
                .tokenSettings(userTokenSettings())
                .build();

        InMemoryRegisteredClientRepository registeredClientRepository = new InMemoryRegisteredClientRepository(tokenExchangeClient1);
        return registeredClientRepository;
    }

Do you know what check is not passed and what might be wrong?
